Let the speed of the first train be (x+5) kmph and the second train be x kmph.

So, distance travelled by first tran(south bound)=2(x+5)


 distance travelled by the second train(due north) is 2x

According to question,

after two hrs the distance between them is 50 km.



solving we get,




So speed of the first train=15 kmph

speed of the second train=10 kmph.
