      Question

      How many seconds will a train 64 m in length, travelling

      at the rate of 40 km an hour, take to pass another train 86 m long, proceeding in the same direction at the rate of 28 km an hour?
      A 34.2 sec Correct Answer Incorrect Answer
      B 36 sec Correct Answer Incorrect Answer
      C 37.8 sec Correct Answer Incorrect Answer
      D 45 sec Correct Answer Incorrect Answer
      E None of these Correct Answer Incorrect Answer

      Solution

      Relative speed = 40 – 28 = 12 km/hr Speed (m/sec) = 12 Γ— (5/18) = 10/3 m/sec Time = Total length of both the trains/Relative speed => Time = (86 + 64)/(10/3) = 45 sec
