  • Question
  • From station M and N, two trains start moving towards each other at speed 125 km/h and 75 km/h, respectively. When the two trains meet each other, it is founds that one train covers 50 km more than another. Find the distance between M and N.?


  • Options
  • A. 190 km
  • B. 200 km
  • C. 145 km
  • D. 225 km

  • Correct Answer
  • 200 km 

    Explanation

    Let the trains meet after time t at a distance x from station N.
    Then another train coming from station M covers a distance of (x + 50)

    For station M,
    (x + 50) = 125t
    ? x = 125t - 50 ..(i)

    For station N,
    x = 75t .....(ii)

    From Eqs. (i) and (ii), we get
    75t = 125t - 50
    ? t = 1h

    Distance between station M and N = 125 + 75t = 200 x 1 = 200 km
