150 m long train running with the speed of 90 km/h to cross a bridge in 26 s .What is the length of the bridge?
Correct Answer: 500 m
Explanation:
Let length of bridge be L m.
We know, Speed = Distance/Time According to the question,
90 x 5/18 = 150 + L/26
⇒ 25 x 26 = 150 + L
⇒ 650 = 150 + L
∴ L = 500 m
