the distance between two stations is 300km. two trains start simultaneously from these stations and move towards each other ,the speed of one them is 7k/hr more than the other . if the distance between them after 2hours of their start is 34km ,find the speed of each train ????

  • math -

    Train #1 = X km/h.
    Train #2 = (X+7) km/h.

    d1 + d2 = 300-34.
    2x + 2(x+7) = 266
    4x + 14 = 266
    4x = 266-14 = 252
    X = 63 km/h.
    X+7 = 63+7 = 70 km/h.
