Answer:

2.5 hours

Step-by-step explanation:

Given the following:

Shuttle that left station at Speed = 15 mph ; passed by a second shuttle which left 20 minutes later traveling at a speed of 17mph.

How far did the first shuttle travel before being passed by the second?

Distance moved by first before the second started:distance = speed × time

D1 = 15 mph × (20/60) = 5 miles

If t = time traveled

d - 5 = 15t - - (1)

d = 17t - - - (2)

17t - 5 = 15t

17t - 15t = 5

2t = 5

t = 5/2

t = 2.5 hours
