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 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 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 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:-

A train crosses a platform of length 250 m in 20 seconds and crosses a pole in 10 seconds. Find the length of train.
