    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
