Question #44299

a car is moving at as speed of 15m/s.what is the time taken by it to cover the distance of 1.2km ?

Expert's answer

As we know,we need to use the formula S=V*T, where S – distance, V – speed and T – time.

That meansthat T = S/V. To calculate this we need to use the same dimensions. Therefore, we need to convert kilometers into meters:

1.2 km =1.2 * 1000 m = 1200 m. (because, as we know, 1km=1000m)

Now we canuse our formula: T=S/V = 1200/15 = 80 s.

We cantransform seconds into minutes (1 min = 60 s). And the answer: 1 min 20 s.
