Quiz for a 60 MPH all day long car

[pooch]

A guy is driving a Model A on a 20 mile trip.

He does 60 MPH for 10 miles, then the engine get a bit hot, so he slows and does 30 MPH for the last 10 miles.

What is his average speed over the whole 20 mile trip?

[WHN]

45 mph, just think of that.

Agreed. The math:

60x10 = 600
30x10 = 300
total 900

900 divided by 20 miles = 45 MPH Average

[pooch]

I have been fined by an average speed camera and disputed the figure.

It has taken a day and a half of research and I still do not quite believe the correct figures, but keep chiming in .

[Patrick L.]

This just tells me not to drive 60 mph and get the engine hot, just drive 45 mph [ or whatever it comes out to be] for the whole trip. [ smiley face]

Pooch, you were obviously not driving Kevins car. Because Kevins car goes 60 mph all of the time!

[Synchro909]

The average speed is 40 mph.
10miles at 60mph takes 10 minutes
10 miles at 30 mph takes 20 minutes
Total time is 30 minutes.
20 miles in 30 minutes gives an average of 40 mph.

Synchro, correct.

Trip takes 30 minutes.

If you were doing 45 MPH you would travel 22 1/2 miles.

The maths formula is T = d / s, where T is the time in hours, D is the dstance and S is the speed.

I am still finding it hard to get my head around it.

The average cams I got done on are 14.1 KM apart.

8.1 KM is 100 KPH, 1.1 KM is 80 KPH, 4.9 KM is 40 KPH.

I thought surely the average speed should be over 70 KPH at least more likely 75 KPH.

The figure I was done on was exceeding 65 KPH , THE AVERAGE SPEED for this section.

OK, I will concede and agree to your calc.

[pooch]

I would do exactly the same before my research.

I reckon 45 MPH should be the average.

You are going 15 MPH faster in the first 10 miles, then 15 MPH slower in the next 10, so it should average out, but it don't.

I am still going to court to fight it, as the bastards have refused to give me any leniency, after me stating that I have had only one ever penalty which was a minor speeding fine in 1983 in my entire history of driving since 1969.

I will not be able to sleep tonight. 40.02 mph?

Hey pooch,
To me HERE, the whole thing about getting 'pinched' over top speed of 45mph on a 20 mi trip ...sounds odd !
'They' changed the speed limit on the street going past my home, to 45mph ! This is in a highly trafficked residential neighborhood. And, no one seems to care, so traffic 55/60 regularly on this street.
So, you in a highly populated residential area doing your trip of 20 mi ?
Always thought that your land was so vast that you would have to go fast to get anywhere in a timely manner
Traffic cameras here are money makers, catching those who 'run' red lights, not speeders per se.

[glenn in camino]

Sorry, My math skills left me when I retired.

[Terry, NJ]

I didn't get the correct answer because I spotted the obvious answer (45MPH) was sucker bait. It was just too easy to arrive at that answer! Cute Riddle!
Terry

[Tinbasher]

Some people have way to much time on there hands. A + B - X + =??? Well it made us think again. LOL JP.

[H. L. Chauvin]

In theory, for a math problem, his Model A averaged 40 mph.

But in reality, since his Model A had mechanical brakes and probably a non-lightened flywheel, he could not go from 60 mph to 30 mph instantly, and he maybe averaged about 45 mph for about 6.39 seconds while slowing down, depending on the weight of his tool box and which way the wind was blowing.

Guy should get credit in that his speedometer and odometer were working to report these exact mileage figures ..... plus appears he did not burn up his engine.

Terry, not a very cute riddle when the bastards want a $341 fine and 2 demerit points.

AND the 40 KPH section says Trucks and Busses speed limit and I was driving a winnebago.

[heneste]

Any idea what the two readings were recorded as? You were running 60 mph for 10miles which is 16.093km. Possibly the two readings were taken within the first 10 mile section (i.e. 60 as the first reading and slightly lower than 60 for the second reading )

[Keith True]

I got caught by the math in the early 80's in Maine.At the toll booth you would get a card,and you would pay different amounts depending on what exit you got off at.What I didn't know was that the cards were time stamped too.I was headed up with an empty trailer for a load of spuds,and that truck was pretty zippy when it was empty.I was pulled over after the last toll booth because they told me there was no way I could have covered those 60 miles in 47 minutes legally.That truck topped out at 72,but the limit then was 55.

NYS was pulling the same crap on the thruway back then.

[Keith True]

All us guys in trucks learned our lesson though.If you lost your card somewhere along the way,you had to pay the maximum amount of the toll.We all ran the total length anyway,so we would just say the card blew out the window.Paid the same amount as if we still had the card.That little idea was given to us by a tolltaker.

[burner31]

Easy answer:

Who cares how long it takes or what the average speed is, you're driving a Model A...enjoy the ride.

I was never good a math anyway.

[Bill G]

Unless it's in a school zone, I almost think a speeding ticket in a Model A would be hard to achieve - even if I tried.

Very interesting. I'd never heard of these kind of tickets, until this thread, and then thought it was only Australia until your post.

When I was driving through Hannibal Missouri a couple years ago I had just topped a hill in town and there was a traffic light half a block on the downhill side, and I got flashed by the camera when the light turned red while I was in the intersection. Thought for sure I'd get a ticket in the mail. but it never happened.

[pooch]

In OZ, the light has to be red before you pass into the intersection.

I once saw the same thing as I just got into an intersection on the orange and I saw a flash of the camera in my mirror, then noticed a car right behind me.

He obviously was the money donor to the law, not me.

I was driving to LeBaron Bonney a while back,and when I crossed the line into Mass.I saw one of those speed display wagons set up on the side of the road.I wasn't going fast,and I figured I would check my accuracy of my old speedo.I turned around and drove by it again.I saw the flashes and didn't pay any attention to them as I wasn't doing anything wrong.A week later I got two tickets in the mail for not wearing a seatbelt.Nice pictures too.I had my 79 Ford plow truck,and it only has lap belts,no shoulder belts.I can't run the plow controls with a shoulder belt on.I drove my truck to my court date,said not guilty and said I really was wearing a belt,just not a shoulder belt.and the truck was in the parking lot if anybody wanted to see it for themselves.The judge just said I'll take your word for it,go home.

[chap52]

A couple of years ago I got my first ticket in over 40 years. Figured I just pay it because of all the violations I had gotten away with over the 40 year span. I was advised that I could take a course and avoid the points on my license. I told the Officer at my age (71)a couple of points won't matter.
It is frustrating though.

[Benson]

New York was timing distances entrance to exit and giving speeding tickets in 1967 and 1969 when I was at Ft. Monmouth, NJ.

It was a well known scam to "lose the ticket" if trip was long enough.

NJ Turnpike was a quarter at every toll plaza.

The scam on NJ Turnpike was to "Pretend" to throw quarter in basket then stop and get out to "look" for the quarter ... "winky winky" ... the toll keeper would wave you through when cars stacked up behind.

If you tried it at next toll plaza they had radioed ahead and knew you were coming!

[RUNNERBUN]

$341 and 2 demerit points, Ouch! I feel your pain. I hope you win the fight. Speaking of the Law of Averages, I learnt a long time ago that the Law of Averages does not work. Here is how you can prove it for yourself. Get two buckets, fill one with freezing water and ice and fill the other with boiling water. Now put one of your feet in freezing bucket and the other foot in the boiling water. On the average you should be very comfortable. See I told you the law of averages doesn't work.

When I did a worldtrip back in 2005, I had many hire cars all over.

I was certainly trying hard to get no tickets, because I know the hassle of it all being offshore when you get home and get the tickets.

When I was in Miami, I came across a toll booth after dark, and it wanted 2 quarters, I was fumbling for a bit when a blast of a horn and headlights on hi beam came from behind.

I was not going to go thru that toll without paying, so I continued to try and find coin.

Several more blasts from behind came, with the dude inching up closer to my back.


I found the coins and threw them in, then gave the guy behind a finger .

I later read that Miami is the murder capital of the USA ...

[Terry, NJ]

The Pa Turnpike was the first to use it in the 1940s, but I don't think it's in use anymore. In NJ, they shortened the cycle of the yellow to get to red faster and then if you're in the intersection, then the camera gets you.But BUT thats not all! It turns out the courts are paying a bounty to the manufactures for each case the court wins! Justice at it's finest!

ya he might murder you not for the finger, but because you took to long.

[Terry, NJ]

No, It's Chicago! It used to be Miami because the Fla. DVM , in it's wisdom, Coded the License numbers so that rental cars could be identified by police. Trouble was the wrong ones got ahold of the codes and could ID out of towners, hence unarmed. Once they figured out what was going on, and with the large number of concealed carry permits issued, it ceased to be problem.

You can get fined for speeding on the French autoroutes if the ticket shows a higher average speed than the speed limit. You used to be stopped by the Gendarmes waiting just the other side of the peage but I presume these days you would just receive a letter in the post. That is definitely not something that going to happen to me in my Model A!

[V4F]

I'm not good at the math , but my car will cruise at 60mph till it runs out of gas .
improved banger , 5 speed , 3.27 gears , quick change .
