Question

Two train leave a railway station at same time. The first train travels due west and second train due north . The first train travels 5km/h faster than the second train . If after 2 hours they are 50km apart find the average speed of each train

Answer 1

Answer:

20

Step-by-step explanation:

Let the speed of the second train = x km/hr

The speed of the first train = x+5 km/hr

Distance covered after two hours by the first train is 2(x+5) km.

Distance covered by the second train after two hours is 2x km.

(2x)^2 + 4(x+5)^2=(50)^2 (Using pythagoras theorem)

Solve

We get x=-20 and x=15

The speed of the first train = 15+5=20km
