Question
Train 'A' having a speed of 15 m/s can cross a man in 8
seconds. The length of train 'B' is 60 metres more than the length of 'A'. If the speed of 'B' is 45 m/sec and both trains are travelling towards each other, then find the time taken by them to cross each other.Solution
Length of train 'A' = 15 × 8 = 120 metres
Length of train 'B' = 120 + 60 = 180 metres
Relative speed = 15 + 45 = 60 m/sec
Required time = (120 + 180) ÷ 60 = 300 ÷ 60 = 5.0 seconds
