Question 99
A train of length 135 m travels at a speed of 54 kmph crosses a bridge in 27 seconds. Find the length of the bridge. (in m)
Solution
Speed of train = 54 kmph = $$54\times\frac{5}{18}=15$$ m/s
Let length of bridge = $$x$$ m
Using, speed = distance/time
=> $$15=\frac{135+x}{27}$$
=> $$135+x=27\times15=405$$
=> $$x=405-135=270$$ m
=> Ans - (A)
