A train travelling with a speed of 90 km/h can cross a pole in 8 seconds. Find the time taken by the train to cross a 300 metres long platform if the speed of train is increased by 25%.
Speed of train = 90 × 5/18 = 25 m/s Length of train = 25 × 8 = 200 metres Desired time = (300 + 200)/(1.25 × 25) = 16 seconds
