    Answer:

    use the concept of relative velocity

    total distance-240 m

    when going in same direction

    240/x-y=60

    x-y=4

    when going in different direction

    240/x+y=3

    x+y=80

    solving the equations we get

    x=42 and y=38

    speed of faster train is 42m/s

    and slower one is 38m/s
