    52 seconds. If the speed of the train is 54 km/hr, then what is the length of the platform?
    A 240 m Correct Answer Incorrect Answer

    C 320 m Correct Answer Incorrect Answer
    D 280 m Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Let the Length of train train be L meter and length of platform be P meter. Speed of train = 54 km/h = 54 × (5/18) = 15 m/s Here, (L /15) = 36 ⇒  L = 540 m Also, (540 + P)/15 = 52 ⇒  540 + P = 780 ⇒  P = 240 m
