Question

A train is traveling at a constant speed of 79 m.p.h.If city A and city B are 395.1 miles apart,about how may hours will I take the train to arrive?

Answer 1

v = 79 mph is the rate of the train

d = 395.1 mi the distance traveled

t = the time of the travel

Since speed = distance/time we have:

v = d/t

Solving for t we have:

t = d/v

Plug the values:

t = 395.1/79

t = 5 hr approximately

The train will need 5 hours
