2. An electric engine has a velocity of 120 km h-1.
How much distance will it travel in 30 s?​

Answer 1

Velocity v = 120 km/h

Time t = 30 s

Let Distance be d

First, we need to convert 120 km/h into m/s

1 km/h = (1000m)/(3600 s) = 5/18 m/s

So, 120 km/h = 120×5/18 m/s

So, v = 200/6 m/s

Now, velocity = distance/time

So d = v×t

So, d = (200/6) × 30

So, d = 1000 m

So, d = 1 km

Thus, distance travelled is 1 km
