    C 11 m/s Correct Answer Incorrect Answer
    D 7 m/s Correct Answer Incorrect Answer
    E 12.5 m/s Correct Answer Incorrect Answer

    Solution

    Speed of train = (Length of train + Length of Platform)/Required time Length of train = 220 m Crossing time of platform = 2 × 60 = 120 sec Length of platform = 220 × 2 = 440 m Let the speed of train be x. Speed of train = (220 + 440)/120 ⇒  x = 660/120 = 5.5 m/s
