    A train 100 m long is running at the speed of 30 km/hr. Find the time taken by train to pass a man standing near the railway line.

    A. 8 sec
    B. 12 sec
    C. 15 sec
    D. 16 sec

    Answer: Option B
    Explanation:
    Speed of the train = 30 km/hr = 30 x 5/18 m/s = (25/3) m/s
    Distance= Length of train = 100 m

    Time taken = Distance/Speed = 100/ (25/3) = 12 sec
