A 540-metre long train takes 9 seconds to cross a pole.
If it takes 33 seconds to cross a bridge, then find the length of the bridge. (in km)Solution
Speed of the train = (540 / 9) = 60 m/s
Distance covered by the train in 33 seconds = 60 × 33 = 1,980 metres
Length of the bridge = 1,980 - 540 = 1,440 metres = (1440 / 1000) = 1.44 km
