Question

a train running at the speed of 30km/hr crosses a pole in 18 seconds what is the length of the train?​

Answer 1

$\huge\underline\mathfrak\color{blue}Answer$

Speed = 30km/hr = 30 * 5 / 18 m/ s

time taken to cross the pole = 18 seconds

speed = distance / time

Here , distance = length of the train

distance = speed * time

distance = 30 * 5/18 * 18 = 150 m

Therefore, length of the train = 150m or 0.15Km.
