Question

If 200 m long train travelling at 60 km per hour takes 1 minute to cross the bridge, then the length of the bridge is

Answer 1

Answer:

The bridge length is 800 meters.

Step-by-step explanation:

Since, if 200 m long train travelling at 60 km per hour takes 1 minute to cross the bridge, then we want to know the length of the bridge.

Then, we know that in one hour, sixty minutes, he travels 60 kilometers, then in one minute he travels 1 kilometers = 1000 meters.

Thus, we have to compute the subtraction of the total kilometers run with the length of the train, then:

1000 - 200 = 800 meters.

Hence, the bridge length is 800 meters.
