    Answer:

    105 mph = rate of first plane

    130 mph = rate of second plane

    Step-by-step explanation:

    Let r = rate of first plane

    then r + 25 = rate of second plane

    2r = distance of first plane

    2(r + 25) = distance of second plane

    2r + 2(r + 25) = 470

    2r + 2r + 50 = 470

    4r = 420

    r = 105 mph

    r + 25 = 130 mph
