Question

Q. 29. An electric train is moving
with a velocity of 120 km/hr. 1
much distance will it cover in 30 s?
PO​

Answer 1

Explanation:

velocity of train = 120 km/hr = 120

$120 \times \frac{5}{18} = \frac{100}{3}ms{ - 1}$

Now, assuming that the train is travelling at constant velocity...

Distance = velocity × time

= 100/3 × 30 = 1000 m

Thus distance covered = 1000 metres or 1km.
