Question
Train A running with a sped of 180 km/h crosses a
vertical pole in 15 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 180 metre long tunnel.Solution
Speed of train A = 180 × 5/18 = 50 m/s Speed of train B = 55 m/s Length of train A = 15 × 50 = 750 metres Length of train B = 750 – 50 = 700 metres Desired time = (700 + 180)/55 = 16 seconds
