Question
Train A running with a sped of 90 km/h crosses a
vertical pole in 9 seconds. Speed of train A is 5 m/s less than speed of train B, and length of train B is 50 metres less than length of train A. Find the time taken by train B to cross a 290 metre long tunnel.Solution
Speed of train A = 90 × 5/18 = 25 m/s Speed of train B = 30 m/s Length of train A = 25 × 9 = 225 metres Length of train B = 225 – 50 = 175 metres Desired time = (175 + 290)/30 = 15.5 seconds
