Question

Solve the word problem.

The formula t =d/r gives the time t for a distance d traveled at a rate r. A train traveled 225 miles at a rate of 45 mi/hr.

How long did it take the train to travel this far?

A.
4.5 hr

B.
5 hr

C.
5.5 hr

D.
6 hr

Answer 1

If you know the covered distance, and average speed, the only thin you have to do is to divide covered distance by average speed.
`225/45=5` It will take 5h to cover this distance by this train with average speed
`45(mi)/(hi)`
