Answer:

The average speed of a car is 20 km/h.

Step-by-step explanation:

We have,

Distance covered by car is 10 km

Time taken by the car to cover that distance is 30 min. 30 min means 0.5 hours.

It is required to find the average speed of a car. It can be calculated using formula of average speed which is given by :


v=(d)/(t)\\\\v=(10\ km)/(0.5\ h)\\\\v=20\ km/h

So, the average speed of a car is 20 km/h.
