Question

a train 200 m long is running at. a speed of 90km/hr how much time will it take to cross 300 m long platform?​

Answer 1

Step-by-step explanation:

total distance= distance of train + distance of platform

=200+300m

=500m

speed=distance/time

90*5/18 =500/time

25=500/time

25*1/500=time

therefore,time=0.05s
