Question

What is the average speed of each plane? (Hint: Since they are traveling in the same direction, the distance between them will be the difference of their distances.)

    Answer:

    Plane 1:  rate = 245 mph

    Plane 2:  rate = 98 mph

    Step-by-step explanation:

    Plane 2:  Let r = rate

                        d = 5r

    Plane 1:    2.5r = rate

                        d = 5(2.5r)

    5(2.5r) – 5r = 735

    12.5r – 5r = 735

    7.5r = 735

    r = 98
