Two trains start at same time from two stations towards each other at the speed of 20 km/hr and 16 km/hr . At the time of meeting the faster train covers 60 km more distance than other . Find the distance between two stations .
Answer & explanation
Correct answer: option 3
Let time of travelling be t hours
Distance travelled by train with speed 16 km/hr = 16 × t = 16t
Distance travelled by train with speed 20 km/hr = 20 × t = 20t
According to question ,
Difference in distance travelled by two trains = 60 km
20t - 16t = 60
4t = 60 ⇒ t = 15
Distance between two stations is = 16t + 20t = 36 × 15 = 540 km
