Question

a train travelling at 60 km per hour takes 18 second to cross a 180 metre long platform find the length of the train​

Answer 1

Lengthof train=X
platform length=180
total distance=x+180
speed=60km/hr=60×5/18=(300/18)m/
Time =18s
Time =Distance/speed
18=X+180/(300/18
18×300=18(X+180)
300=X+180
x=300-180=120
so length of the train=120m
