2 trains going opposite directions leave at the same time. Train b is 10mph faster than train a. in 8 hours the trains are 960 miles apart. find the speed of each

  • math - ,

    X MPH = train a speed,
    (x + 10) mph = train b speed,

    d1 + d2 = 960 m1,
    8x + 8(x + 10) = 960,
    8x + 8x + 80 = 960,
    16x + 80 = 960,
    16x = 960 - 80,
    16x = 880,

    x = 55 mph,
    (x + 10) = 55 + 10 = 65 mph.
