Question

an electric train is moving with a velocity of 120km/h. how much distance will it move in 30sec​

Answer 1

Given velocity of train is 120 km/h

Time = 30 sec

$\frac{30}{60} \times \frac{1}{60} \\ \\ = \frac{130}{360} \\ \\ = \frac{1}{120}$

Distance = Speed × time

$= 120 \times \frac{1}{120} \\ \\ =1km$
