Paul drove for one and a half hours at 65 mph before he realized he had forgotten his wallet. How far was he from home?

Answers

He drove for one and half hours = 1 1/2 = 1.5 hours.

Speed = 65 miles per hour.

Distance = Speed * Time

Distance = 65 miles/hour * 1.5 hours

Distance = 97.5 miles

So Paul was 97.5 miles from home.
