    Since the two trains are moving in same direction, the relative speed

    = (50 - 39)= 20 kmph

    = 20×5/18
    = 50/9 m/sec.

    Length of the fast train = 50/9x18
    =100 m
    ×
    44
    = 220 metres.

    Speeds of two trains=50 and 30
    in same direction speed=50-30=20km/hr=20*5/18=50/9 m/sec
    and distance=speed*time=50/9*18=100m
