  1. d = 132/1000 = .132
    t = 6 / 3600 = .00166
    speed = .132/.00166 = 79.2 km/hr

  2. Correct option is
    C
    79.2 km/hr
    Speed of train =
    Time taken to pass the pole
    Length of train

    =
    6
    132

    m/sec=22m/sec=(22×
    5
    18

    )km/hr=79.2km/hr

  3. Train length=132m
    Time taken = 6s

    Speed = length/time
    = 132/1000 / 6/3,600
    = 0.132/0.00166 km/hr
    = 79 km/hr
