Question
A high-speed train moves at 45 m/s and crosses a stationary pole in 16 seconds. Calculate the approximate time required for the train to cross a 1200-metre-long tunnel.
Solution
ATQ,
Length of the train = 16 × 45 = 720 metres
Time taken to cross the tunnel = (720 + 1200)/45 = 1920/45 = 42.67 seconds or 43 secs
