Question
Train 'A' and Train 'B' pass each other in 10 seconds
when moving in opposite directions. If Train 'A' takes 12.5 seconds to pass a pole, and the speeds of Train 'A' and Train 'B' are 12 m/s and 13 m/s, respectively, find the length of Train 'B'.Solution
Length of train 'A' = 12 X 12.5 = 150 metres Let the length of train 'B' be 'x' metres. So, 150 + x = 10 X (12 + 13) Or, 150 + x = 250 Or, x = 100 So, length of train 'B' = 100 metres
