      seconds it will take to cover a distance of 5/8 km?
      A 40 sec Correct Answer Incorrect Answer
      B 30 sec Correct Answer Incorrect Answer
      C 25 sec Correct Answer Incorrect Answer
      D 50 sec Correct Answer Incorrect Answer

      Solution

      Speed of train = 45 km/hr Speed of train in (m/sec) = 45 x 5/18 = 12.5 m/sec Distance = 5/8 of 1 km = 5/8 x 1000 m = 625 m Therefore, Speed = distance/time 12.5 = 625/t Time = 625/12.5 = 50 sec
