Let the length of train ‘A’ be ‘x’ metres Therefore, length of the goods train = ‘4x’ metres Speed of train ‘A’ = 130.5 × (5/18) = 36.25 m/s According to the question, 4x + x = 36.25 × 48 => 5x = 1740 => x = 348 Therefore, time taken by train ‘B’ to cross train ‘A’ = {(348 + 60)/(48 + 20)} = 6 seconds
