A train moves at the speed of 40 m/s and crosses a bridge of length 550 metres in 25 seconds. What is the length (in metres) of the train?
Let length of train = $$l$$ m
Length of bridge = 550 m
Speed of train = 40 m/s and time taken = 25 seconds
Using, speed = distance/time
=> $$40=\frac{l+550}{25}$$
=> $$l+550=40\times25=1000$$
=> $$l=1000-550=450$$ m
=> Ans - (B)
