    Question

    1440 metres long train crosses a man who is moving in

    the same direction with a certain speed in 32 seconds. If the same train can cross a pole in 24 seconds with the same speed, then find the speed of the man.
    A 14 m/sec Correct Answer Incorrect Answer
    B 15 m/sec Correct Answer Incorrect Answer
    C 12 m/sec Correct Answer Incorrect Answer
    D 16 m/sec Correct Answer Incorrect Answer

    Solution

    Let the speed of the man be ‘x’ m/sec. Speed of train = 1440/24 = 60 m/sec Relative speed of the train = (60 – x) m/sec According to the question, => (60 – x) = 1440/32 => x = 60 – 45 => x = 15 Therefore the speed of the man = 15 m/sec
