Question
Train A running with a sped of 126 km/h crosses a
vertical pole in 12 seconds. Speed of train A is 6 m/s less than speed of train B, and length of train B is 85 metres less than length of train A. Find the time taken by train B to cross a 280 metre long tunnel.Solution
Speed of train A = 126 × 5/18 = 35 m/s Speed of train B = 41 m/s Length of train A = 12 × 35 = 420 metres Length of train B = 420 – 85 = 335 metres Desired time = (335 + 280)/41 = 15 seconds
