two trains A and B ,each of length 100 m , are running on parallel tracks. One overtakes the other in 20 s and one cross the other in 10 s. calculate the velocities of each train.

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

Two trains, each of length 200 m are running on parallel tracks. One overtakes the other is 20 s and one crosses the other in 10 s. The velocities of the two trains are

Two trains A and B each of length 200m are running on parallel tracks. A overtake B in 30s and A crosses B in 15s. What are the velocities of trains A and B?

Two trains A and B of length 100m and 200m , respectively, are approaching each other on parallel tracks. If they take 15 s to pass each other and velocity of A is three that of B , find their velocities.

two trains A and B,each of length 100 m, in length are running in opposite driection on parallel tracks with velocities 40 kmh ^(-1) and 32 kmh^(-1) . In what time will they completely cross each other ?

Two trains each of length 50m. are running with constant speeds on parallel tracks. While moving in same direction one over takes the other in 40 seconds and while moving in opposite direction on ecrosses the other in 20 seonds. The speeds of trains will be:-
