The Car Problem Riddle

A man drives one mile at 30 mph.
How fast must he drive the second mile to average 60 mph for the total two-mile trip?

👉 It’s impossible.

To average 60 mph over 2 miles, he must complete the trip in 2 minutes (since 2 miles Ă· 60 mph = 2 minutes).

  • The first mile at 30 mph takes 2 minutes.
  • That means there is NO TIME LEFT to complete the second mile.

Even if he drove infinitely fast, he still wouldn’t reach the required average speed.
