Two trains start at same time from two stations towards each other at the speed of 22 km/hr and 18 km/hr . At the time of meeting the faster train covers 120 km more distance than other . Find the distance between two stations .

1200 km

Let time of travelling be t hours 

Distance travelled by train with speed 22 km/hr = 22 × t = 22t 

Distance travelled by train with speed 18 km/hr = 18 × t = 18t 

According to question , 

Difference in distance travelled by two trains = 120 km 

22t - 18t = 120 

4t = 120     ⇒     t = 30 

Distance between two stations is = 22t + 18t = 40 × 30 = 1200 km
