Question
Two trains, 'A' and 'B', are heading towards each other
from opposite ends of a 360-meter bridge. Train 'A' travels at a speed of 15 m/s, and train 'B' travels at a speed of 25 m/s. Calculate the distance between the point where the trains meet and the point where train 'A' starts entering the bridge.Solution
Distance to be covered by the trains before meeting for the first time = 360 metres Relative speed of the two trains = 15 + 25 = 40 m/s So, time taken to meet = 360 ÷ 40 = 9 seconds Distance covered by train 'A' in 9 seconds = 15 X 9 = 135 metres
