Train ‘A’ running with a speed of 63 km/hr can cross a standing goods train of 4 times its length in 24 seconds. Find the time taken by 150 metres long train ‘B’ which is coming from opposite direction of train ‘A’, with a speed of 15 m/s, to cross train ‘A’.
Let the length of train ‘A’ be ‘x’ metres Therefore, length of the goods train = ‘4x’ metres Speed of train ‘A’ = 63 × (5/18) = 17.5 m/s According to the question, 4x + x = 17.5 × 24 => 5x = 420 => x = 84 Therefore, time taken by train ‘B’ to cross train ‘A’ = {(84 + 150)/(24 + 15)} = 6 seconds
