Question
Train ‘A’ running with a speed of 36 km/hr can cross
a standing goods train of 4 times its length in 30 seconds. Find the time taken by 285 metres long train ‘B’ which is coming from opposite direction of train ‘A’, with a speed of 39 m/s, to cross train ‘A’.Solution
Let the length of train ‘A’ be ‘x’ metres Therefore, length of the goods train = ‘4x’ metres Speed of train ‘A’ = 36 × (5/18) = 10 m/s According to the question, 4x + x = 10 × 30 => 5x = 300 => x = 60 Therefore, time taken by train ‘B’ to cross train ‘A’ = {(60 + 285)/(30 + 39)} = 5 seconds
