A 600 metres long train can cross a 1200 metres long platform in 36 seconds. In how much time(in seconds) can it cross a bridge 2200 metres long?
Answer & explanation
Correct answer: option 1
We know ,
Speed = \(\frac{Distance }{Time}\)
Speed of train = \(\frac{600 + 1200}{36}\) = 50 m/sec
Now , Time taken by train to cross 2200 m long bridge
= \(\frac{600 + 2200}{50}\)
= 56 m/sec
So , 2200 m bridge is cross the bridge in 56 sec
