    1322 metres long train crosses a man who is moving in

    the same direction with a certain speed, in 40 seconds. If the same train can cross a tree in 20 seconds with the same speed, then find the speed of the man.
    A 33.05 m/sec Correct Answer Incorrect Answer
    B 30.05 m/sec Correct Answer Incorrect Answer
    C 36.05 m/sec Correct Answer Incorrect Answer
    D 22.05 m/sec Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Speed of train = 1322/20 = 66.1 m/sec Let the speed of the man be ‘s’ m/sec Relative speed of the train = (66.1 – s) m/sec According to the question, (66.1 – s) = 1322/40 Or, s = 66.1 – 33.05 = 33.05 Therefore, speed of the man = 33.05 m/sec
