  • Question
  • Two trains of equal length are running on parallel lines in the same direction at 46 km/hr and 36 km/hr. The faster train passes the slower train in 36 seconds. The length of each train is:


  • Options
  • A. 50 m
  • B. 72 m
  • C. 80 m
  • D. 82 m

  • Correct Answer
  • 50 m 

    Explanation
    Let the length of each train be x metres.

    Then, distance covered = 2x metres.

    Relative speed = (46 - 36) km/hr

       = 10 x 5 ❩m/sec
    18

       = 25 ❩m/sec
    9

    2x = 25
    36 9

    ⟹ 2x = 100

    x = 50.
