Dang! She beat me too.

You’re right. How come somebody hasn’t started a “wisdom” club?
My experience is the higher the IQ the less stable, but that’s for very high IQ’s.
Is it genetic or environmental?
Dang! She beat me too.
no “return trip” mentioned.
The ‘return trip’ mentioned was part of the comment I referred to. It wasn’t my post. I only copy and pasted his post and answered it.
My opinion, for whatever it is worth - (I could probably qualify for Mensa, but don’t get the point).
The question isn’t worth spending one minute of our precious time here on earth, for it offers no information about human talents unrelated to intelligence.
Only fools think IQ tests are a measure of their worth. God makes fools of these sad people.
Wrong-o, wrong-o.
The average speed for NASCAR drivers isn't calculated by averaging their lap speeds, but by calculating their average speed according to elapsed time over distance covered.
It has ever been thus...
See #87
“The car is still at the top of the hill.”
No. It is in Alpha Centauri and still decelerating.
Here is another of the questions Wertheimer sent to Einstein.
The answer is deceptively simple. hint..if you are doing a bunch of calculations you are going about it in the wrong way.
4.Amoeba Propagation An amoeba propagates by simple division; each split takes
3 minutes to complete. When such an amoeba is put into a glass container with a nutrient
fluid, the container is full of amoebas in one hour. How long would it take for the container
to be filled if we start with not one amoeba, but two?
57 minutes
its not asking for the average speed. its asking for the speed for the second half of the trip to be averaged with the first half of the trip to complete the trip at an average of 30 mph. An average of 30 mph means you you complete the ENTIRE trip in 4 minutes. it takes you 4 minutes to do the first half, so there is no time left to do the second part.
So that's my problem ;-)
Oh, I get it. It’s a trick question. The ‘length’ is artificially divided in ‘half’, limiting the speed during that first half so that it takes at least 4 minutes.
Then both miles are lumped together and the time is used to calculate AVE MPH.
I understand that AVE MPH is based on distance per time, so I see how the 15 mph limit ensures that there is not a possible answer.
However, I don’t like rigged tests. SO.... here’s my answer (I have my own ‘tricks’)
Take the car to a Custom Auto shop and have nitrous installed. Don’t tell the guys who are timing you. Once you head off up the hill, engage the nitrous. This will give you plenty of speed to ensure you can go fast enough on the downhill side to make it there in four minutes.
Now to it. I hope be forgiven going off topic. It was the redoubtable Potter St Elementary School, Northwood Hills, where in 1946, 14 year olds were pushed out into the world. I was one of them. For it was work, work and more work. Listening to old men moaning about things had changed. How well did I come to know Northwood. We took our place in the hard scrabble post war years. Luckier than our predecessors in the horible 1930's. Elton John got his start at the Northwood Hotel, but was from nearby Pinner.
Another ramble, but enough said by me. Good luck to the "young uns".
Your riddle does not resemble the problem posed at all: the problem stipulates that the vehicle in question has already traveled 1 mile, while your riddle is completely a priori.
Tch, tch. Any time someone speaks of velocity, time is DISTINCTLY part of the issue. Re-take Physics 101, wherein you will be sharply disabused of any notion to the contrary.
