An old clattery auto is to drive a stretch of 2 miles, up and down a hill, /\. Because it is so old, it cannot drive the first mile -the ascent- faster than with an average speed of 15 miles per hour.
Question: How fast does it have to drive the second mile -on going down, it can of course,go faster- in order to obtain an average speed (for the whole distance) of 30 miles an hour?
I'll send a picture of my right big toe for the winner.
Eistein didn't figure out the solution immediately. |

"I don't think it's possible"
We have a winner !! It is not !
The road up is one mile long. The car travels fifteen miles per hour, so it takes four minutes (one hour (60 minutes) divided by fifteen) to reach up the top.
How long does it take the car to drive up and down the hill , with an average speed of thirty miles per hour ?
The road up and down is two miles long. Thirty miles per hours translstes into two miles per four minutes. Thus, the car needs four minutes to drive the entire distance. But these four minutes were already used up by the time the car reached the top. |

I don't think it possible either. If he needs to do it in an average of 30mph then the entire journey HAS to take 2 mins. He's already taken 4 mins to get to the top of the hill.  |

Where did the four minutes come from again? |
