Question
Length of train 'X' is (35n - 30) metres, which is 200 metres more than that of train 'Y'. Time taken by 'X' and 'Y' to cross a pole is 20 seconds and 16 seconds, respectively. Sum of speeds of both the trains is (3n + 1) m/s. Determine the time taken by 'Y' to cross a platform of length 275 metres.
4 X (35n - 30) + 5 X (35n - 230) = (3n + 1) X 80 Or, 140n - 120 + 175n - 1150 = 240n + 80 Or, 75n = 1,350 Or, 'n' = 18 Length of 'Y' = 600 - 200 = 400 metres Speed of 'Y' = (400/16) = 25 m/s Required time = (400 + 275) ÷ 25 = 27 secondsMore Trains Questions
