What is the speed of a train?
Statement I: The train crosses a pole in 10 seconds.
Statement II: The length of the train is 240 metres.
Statement III: The train crosses a platform of equal length in 20 seconds.
From I and II, Speed = 240/10 = 24 m/sec. From II and III, Speed = 240/20 = 12 m/sec. From II and either I or III, we can find the speed of the train.
