Question
A 600-metre long train takes 12 seconds to cross a pole.
If it takes 48 seconds to cross a bridge, then find the length of the bridge.Solution
Speed of the train = (600 / 12) = 50 m/s
Distance covered by the train in 48 seconds = 50 × 48 = 2,400 metres
Length of the bridge = 2,400 600 = 1,800 metres = (1800 / 1000) = 1.8 km
480 ÷ 10 + 18 % of 160 + ? * 9 = 60 * √36
