Two trains of length 150 m and 250 m run on parallel lines. When they run in the same direction it will take 20 seconds to cross each other and when they run in opposite direction it will take 5 seconds. Find the speeds of the two trains. (in km/h)

Two trains of equal lengths take a minute to cross each other when traveling in the same direction.They take 20 seconds to cross each other when traveling in opposite directions. Find the ratio of the speeds of the faster and the slower train.

Two trains of length 110 m and 90 m are running on parallel lines in the same direction with a speed of 45 km/h and 50km/h respectively . In what time will they pass 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:-
