Question

a train 120 M long Travels at the speed of 60 km per hour how long will it take to cross a platform of length 180 m

Answer 1

length of the train=120m
speed=60 km per hour=60000/3600=50/3m per sec
length of the platform = 180m

total distance to be covered = 120 +180 =300m
50/3m= 1sec
1m= 3/50 sec
300 m = 3/50*300
=18 sec
