  • Question
  • The two trains of lengths 400 m, 600 m respectively, running at same directions. The faster train can cross the slower train in 180 sec, the speed of the slower train is 48 kmph. Then find the speed of faster train ?


  • Options
  • A. 68 kmph
  • B. 52 kmph
  • C. 76 kmph
  • D. 50 kmph

  • Correct Answer
  • 68 kmph 

    Explanation

    Let the speed of the faster train be 'X' kmph,
    Then their relative speed= X - 48 kmph
    To cross slower train by faster train,
    Distance need to be cover = (400 + 600)m = 1 km. and
    Time required = 180 sec = 180/3600 hr = 1/20 hr.
    Time = Distance/Speed
    => 1/20 = 1/(x-48)
    X = 68 kmph
