Question
The distance between two stations A and B is 900 km. A
train starts from A and moves towards B at an average speed of 30 km/hr. Another train starts from B, 20 minutes earlier than the train at A, and moves towards A at an average speed of 40 km/hr. How far from A will the two trains meet ?Solution
Distance covered by 2nd train in 20 minutes = (20/60) × 40 = 40/3 km Remaining distance = 900 – (40/3) = 2660/3km Time after which they will meet = [(2660/3)/70] hours Distance covered from A in this time = (2660/210) × 30 = 380 km
