Question

The speed of a train 150 m long, is 45 km/hr. How much time will it take to cross a platform which is 500 m long?

Answer 1

The speed of a train 150 m long, is 45 km/hr. How much time will it take to cross a platform which is 500 m long?-

It will take 52 Seconds to cross the platform.

Step-by-step explanation:

Train length=500 meter.

Platform length=150 meter.

Total length need to be crossed is 500+150=650 meter.

Now, Speed of the train is 45 Kilometer/hour, which means 45000 meter in 3600 seconds.

so we can simply say that this train will require 3600/45000 seconds to travel 1 meter.

In this way for 650 meter it will require-

(3600/45000)*650 seconds=52 seconds.

Answer 2

Dear Student,

◆ Answer -

Time taken = 52 s

● Explanation -

Speed of the train in m/s is -

Speed = 45 × 1000/3600

Speed = 12.5 m/s

Total distance train has to cover for crossing a platform is -

Total distance = 500 + 150

Total distance = 650 m

Time taken to cross train platform -

Time = distance/speed

Time = 650/12.5

Time = 52 s

Therefore, train will take 52 s to cross platform.

Best luck dear...
