Two trains leave a railways station at the same time. The first train travels due south and the second train due north. The first train travel 5km/h faster than the second train. If after two hours, they are 50 km apart, find the average speed of
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.
