      other. A train traveling at a speed of 90 km/hr passes the first pole in 5 seconds and reaches the second pole in 13 seconds. What is the distance between the two poles?
      A 50 metres Correct Answer Incorrect Answer
      B 125 metres Correct Answer Incorrect Answer
      C 150 metres Correct Answer Incorrect Answer
      D 200 metres Correct Answer Incorrect Answer
      E None of these Correct Answer Incorrect Answer

      Solution

      Speed of train = 90 Γ— 5/18 = 25 m/s Length of the train = 25 Γ— 5 = 125 metres Let the distance between the poles be x metres (125 + x)/13 = 25 Or, 125 + x = 325 Or, x = 200 metres Hence, option d.
