Two trains, each of length 100 m, are running on parallel tracks. One overtakes the other in 20 seconds and one crosses the other in 10 second. Calculate the velocities of each train?

Let u and v be the velocity of two trains A and B. While overtaking the relative velocity of train A w.r.t B = u -v.

While crossing, the relative velocity of train A w.r.t B = u+ v.

Total distance to be travelled by car A while crossing = 100 + 100 = 200
