To find the length of the train with the given speed 80km/h and crosses the pole in 7 seconds
let the length(distance) be x
given speed = 80 km/h
= 80 X 1000/3600 m/sec
=22.2 m /sec
Time = 7 seconds
therefore, the distance = speed X time.
x = 22.2 m/sec X 7 sec
x = 155.4 m
the length of the train is 155.4 m
