Question

A car traveled at an average speed of 50 miles per hour for a trip of 225 miles. How long did the trip take ?

Answer 1

4.5 hours

Explanation:

S (speed) = d (distance)/t (time)

solving for t, t=d/s

t=225/50

t=4.5

Answer 2

4.5

Explanation:

Formula

d = r * t

Givens

d = 225 miles

r = 50 mph

t = ???

Solution

d = r * t Substitute

225 miles = 50 mph * t Divide by 50 on both sides

225/50 = 50*t / 50 Do the division

4.5 = t

The trip took 4.5 hours.
