Question
Train A running with a sped of 198 km/h crosses a
vertical pole in 10 seconds. Speed of train A is 6 m/s less than speed of train B, and length of train B is 90 metres less than length of train A. Find the time taken by train B to cross a 211 metre long tunnel.Solution
Speed of train A = 198 × 5/18 = 55 m/s Speed of train B = 61 m/s Length of train A = 10 × 55 = 550 metres Length of train B = 550 – 90 = 460 metres Desired time = (460 + 211)/61 = 11 seconds
