speed of train = distance / time
v = 450 / 22.5
v = 20 m/s = 72km/hr

Distance covered by train in crossing the pole = length of the train = 450m
Time taken in crossing the pole = 45/2 seconds
Therefore, speed of the train = distance /time =450 / 45/2m/s = 20m/s
20 * 18/5 km/h=72 km/h
Time taken in crossing the pole = 45/2 seconds
Therefore, speed of the train = distance /time =450 / 45/2m/s = 20m/s
20 * 18/5 km/h=72 km/h
thanks for
help
you're welcome
