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 of lengths 150m and 180m respectively are running in opposite directions on parallel tracks.If their speeds be 30km/hr . and 24km/hr ,respectively,then they cross each other in

Two trains of length 190 m and 210 m respectively, are running in opposite directions on parallel tracks. If their speeds are 40 km/hr and 32 km/hr respectively in what time will they cross each other?

Two trains 85 m and 155 m long, runat the speeds of 62 km/h and 82 km/h respectively, in opposite directions on parallel tracks. The time which they take to cross each other is:

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 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 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 100 m and 60 m long are moving in opposite direction on parallel tracks. The velocity of the shorter train is 3 times that of the longer one. If the trains take 4s to cross each other, the velocities of the trains are

Two trains A and B 100 m and 60 m long are moving in opposite direction on parallel tracks. The velocity of the shorter train is 3 times that of the longer one. If the trains take 4s to cross each other, the velocities of the trains are

Two trans A and B 100 m and 60 m long are moving in opposite direction on parallel tracks. The velocity of the shorter train is 3 times that of the longer one. If the trains take 4s to cross each other, the velocities of the trains are
