Question

The length of a train is 300 meter and length of the platform is 500 meter. If the speed of the train is 20 m/sec, find the time taken by the train to cross the platform.

Answer 1

Answer:

40 seconds.

Step-by-step explanation:

Distances needs to be covered to cross the platform is  =  Sum of the lengths of the train and platform  

So, distance traveled to cross the platform is  

=  300 + 500

=  800 meters  

Time taken to cross the platform is        =  Distance / Speed  

                                                                =  800 / 20

=  40 seconds

Hence, time taken by the train to cross the platform is 40 seconds.
