      Question

      A pedestrian walking at 6 km/h is overtaken by a train

      running at three times the speed of the pedestrian. If it takes 9 seconds to cross him, find the trainтАЩs length.
      A 30 m Correct Answer Incorrect Answer
      B 25 m Correct Answer Incorrect Answer
      C 40 m Correct Answer Incorrect Answer
      D 22 m Correct Answer Incorrect Answer

      Solution

      ATQ,

      Speed of the pedestrian = 6 ├Ч (5/18) = 1.67 m/s

      So, speed of the train = 1.67 ├Ч 3 = 5.01 m/s

      Let the length of the train be 'x' metres

      ATQ:

      x / (5.01 - 1.67) = 9

      So, x = 30

      Length of the train = 30 metres
