total distance travelled by the train to cross platform= 150+ 450=600m
time taken to cross platform=20sec
velocity of train=600/20=30m/s= 30×18/5= 6×18 =108km/h
time taken to cross platform=20sec
velocity of train=600/20=30m/s= 30×18/5= 6×18 =108km/h

Total distance = 600 m
Time taken 20 sec
Speed= 600/20 m/s
= 30m/s
This speed in km/h = (30 * 18)/5
= 6*18=108 km/h
Time taken 20 sec
Speed= 600/20 m/s
= 30m/s
This speed in km/h = (30 * 18)/5
= 6*18=108 km/h
