      Question

      Two trains 165 metres and 135 metres in length are

      running towards each other on parallel tracks, one at the rate 70 km/hr and another at 38 km/hr. In how many seconds will they be clear of each other from the moment they meet?
      A 12 seconds Correct Answer Incorrect Answer
      B 10 seconds Correct Answer Incorrect Answer
      C 15 seconds Correct Answer Incorrect Answer
      D 6 seconds Correct Answer Incorrect Answer
      E 9 seconds Correct Answer Incorrect Answer

      Solution

      Required time = Sum of the lengths of trains / Relative speed Relative speed = 70 + 38 = 108 kmph = (108 × 5)/18 = 30 m/sec Required time = (165 + 135)/30 = 300/30 = 10 seconds
