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
