Question

    A 120-meter-long train crosses a pole in 6 seconds. How

    much time will it take to cross a 180-meter-long platform?
    A 12 seconds Correct Answer Incorrect Answer
    B 15 seconds Correct Answer Incorrect Answer
    C 18 seconds Correct Answer Incorrect Answer
    D 20 seconds Correct Answer Incorrect Answer

    Solution

    Speed of the train = Length of the train / Time taken to cross the pole = 120/6 = 20 m/s. Total distance to be covered when crossing the platform = Length of train + Length of platform  = 120 + 180 = 300 meters. Time taken = Distance / Speed = 300/20 = 15 seconds. Correct Option: b
