Given :
A train running at a speed of 72 km / hr takes 25 seconds to cross an electric pole.
Formula used :
Distance = speed × time
1 m / sec = (18/15) km/hr
Calculation :
Length of train = distance
speed convert km/hr to m/sec
= 72 = (5/18)
= speed = 20m/ sec
Distance = 20 × 25
= 500 m
Therefore, the length of the train is 500 m
