Question
Train A when travelling with a speed of 144 km/h crosses
a pole in 6 seconds. Find the time taken by the train A to cross another train B of length 25% more than that of train A which is coming from the opposite direction with a speed of 126 km/h.Solution
Speed of train A = 144 × 5/18 = 40 m/s
Length of train A = 40 × 6 = 240 metres
Length of train B = 1.25 × 240 = 300 metres
Speed of train B = 126 × 5/18 = 35 m/s
Relative speed = 40 + 35 = 75 m/s (opposite direction)
Total distance = 240 + 300 = 540 metres
Desired time = 540/75 = 7.2 seconds
