Let the length of the plat form be ‘x' m

Given that , the length of the train is 310m and it crosses a platform in one minute or 60 seconds and also given that the speed of the train is 54 km/hr

We know that , distance= speed ×time

Speed of the train= 54000/60×60

=15m/s

The distance travelled by train after crosses the train is 310+x

Length of the platform=speed ×time

310+x = 15×60

310+x=900

x=590m

Therefore, the length of the platform is 590m

hope it helps.
