Question

Two trains leave the train station at 10:00 a.m. and travel in opposite directions. Their rates are 65 mph and 85 mph. How many hours will it take for them to be 450 miles apart?

Answer 1

Explanation:

The distance between trains increases by 65+85 = 150 mph.

450 miles × (1 hour)/(150 miles) = 3 hours
