Question

a train 200m long, is running at a speed of 90km hr how much time will it take to cross a railway station 300m long?

Answer 1

length of train =200m

speed=25m/s

length of station=300

s=d/t

25=200+300/t

time=500/25

time =20 second

Answer 2

Length = 200 mts
speed = 90 Kmph =90*(5/18) =25 mps
length of railway station = 300 m
Let time taken to cross railway station be x
speed = distance / time
time = distance / speed
x= (200+300)/(25)
x=500/25=20
so train takes 20 seconds to cross a railway station of 300m
