Below is my favorite question of all time. It has been years since it was recounted to me so I can’t attribute it; however I always end up pulling it out in conversations to have a bit of fun with guests, especially those with math, engineering or physics backgrounds.
Scenario:
You have a one mile race track in the shape of a loop. A man is wants to race around the track twice with an average speed of 60 miles per hour. The racer completes the first lap going 30 m.p.h.
Question:
How fast does the racer have to go on the second lap to make his average speed 60 m.p.h over the 2 lap race?
Hint: If the answer were 90 m.p.h, this wouldn’t be a very good question would it?
