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
