  • Question
  • A 200 m long train passes a motorcycler, running in the same direction at 12 km/hr, in 15 second and a jeep travelling in the same direction in 20 s. At what speed is the car travelling (length of both the motorcycler and jeep is negligible)?


  • Options
  • A. 36 kmph
  • B. 32 kmph
  • C. 29 kmph
  • D. 24 kmph

  • Correct Answer
  • 24 kmph 

    Explanation

    Let the speed of the train be 'S' kmph

    From the given data,

    Distance = Length of train = D = 200 mts = 200 x 18/5 kms

    Time = 10 sec

    given speed of the motorcycler = 12 kmph

    Relative speed as they are moving in the same direction = (S - 12) kmph

    ( S - 12)   =   200   x   18 5 15 S   -   12   =   48 S   =   60   kmph  

    Hence, the speed of the train = S = 60 kmph

    Now,

    Let the speed of the jeep be 'x' kmph

    60   -   x   =   200   x   18 5 20 60   -   x   =   36 x   =   60   -   36 x   =   24   kmph

     

    Therefore, the speed of the jeep = x = 24 kmph.
