80km/hr means 80×5/18 = 200/9 m/s
ok length of train is L = 200/9×9 =200m

length of train is equal to the distance travelled by the train in given time with given velocity.
=>
Velocity = 80km/hr
Time = 9sec
=>
Velocity = 80/3600 km/s
=>
Distance travelled by train = Velocity ×Time taken.
=>
Distance travelled by train = 80×9/3600km
=>
= 0.2km = 200m
