    Question

    770 metres long train crosses a man who is moving in the same direction with a certain speed, in 35 seconds. If the same train can cross a tree in 22 seconds with the same speed, then find the speed of the man.

    A 10 m/sec Correct Answer Incorrect Answer
    B 12 m/sec Correct Answer Incorrect Answer
    C 13 m/sec Correct Answer Incorrect Answer
    D 11 m/sec Correct Answer Incorrect Answer

    Solution

    Speed of train = 770/22 = 35 m/sec Let the speed of the man be ‘s’ m/sec Relative speed of the train = (35 – s) m/sec According to the question, (35 – s) = 770/35 Or, s = 35 – 22 = 13 Therefore, speed of the man = 13 m/sec
