Question
A 150-metre train takes 6 seconds to cross a pole. If
the same train takes 12 seconds to cross train 'C' that is travelling in opposite direction at 20 m/s on a parallel track, then find the length of train 'C'.Solution
ATQ, Speed of train 'A' = (150 ÷ 6) = 25 m/s Let the length of train 'C' be 'x' metres. ATQ; (150 + x) ÷ (25 + 20) = 12 Or, 150 + x = 540 So, 'x' = 540 - 150 = 390 Therefore, length of train 'C' = 390 metres
