Question

22. The distance between two stations A and B is 200 km. Two trains start at the same time fron
and B in the opposite directions towards each other. After 2 hours
, the distance between the
50 km. If the speed of one train is 5 km/h more than the other train, find their speed.​

Answer 1

Answer:

distance between the stations = 200 km

Let the speed of one train be x km/h

so, the speed of the other train is (x+5) km/hr

distance covered by first train in 2 hours = 2x km

distance covered by second train in 2 hours =

2(x+5) km = 2x + 10 km

so, according to the question

$2x + 2x + 10 + 50 = 200$

$4x + 60 = 200$

$4x = 200 - 60$

$4x = 140$

$x = \frac{140}{4}$

$x = 35$

so, the speeds of the trains are 35 km/hr and

40 km/hr

hope it helps
