Question
A bullet train running at 65 m/s takes 10 seconds to pass a
tree completely. Determine the approximate time required to cross a 1500-metre-long bridge.Solution
ATQ,
Length of the train = 10 × 65 = 650 metres
Time taken to cross the bridge = (650 + 1500)/65 = 2150/65 = 33.08 seconds or 33 secs
