      Question

      A train moving at a speed of 50 m/s crosses a pole in 12

      seconds. Determine the time required for the train to pass a 800-metre-long platform.
      A 20 secs Correct Answer Incorrect Answer
      B 28 secs Correct Answer Incorrect Answer
      C 32 secs Correct Answer Incorrect Answer
      D 34 secs Correct Answer Incorrect Answer

      Solution

      ATQ,

      Length of the train = 12 Ă— 50 = 600 metres

      Time taken to cross the platform = (600 + 800)/50 = 1400/50 = 28 seconds
