A train 100 m long crosses a pole in 5 seconds.Find the speed of the train in kilometre per hour.

In-s [12.5K]

Answer:

$\sf72 km/h$

Step-by-step explanation:

Distance covered by the train in crossing the pole = 100 m.

$\sf Time \: taken=5 \: seconds$

$\sf \: Speed \: of \: the \: train = \frac{Distance }{Time}$

$\sf = \frac{100}{5} \: m/s$

$\sf \: = 20 \: m/s$

$\sf \: = 20 \times \frac{18}{5} \: km/h$

$\sf = 72 \: km/h$

Hence, the speed of the train is 72 km/h
