A car travels 300 km in 6 hours. What's the average speed of the car? O 50 km/h O 65 km/h O 45 km/h O 75 km/h​
MAXImum [283]

Answer:

50 km/h

Explanation:

The average speed of the car is essentially the same thing as the unit rate.

Here a car goes 300 km for every 6 hours. To find the unit rate, we must find how many kilometers it goes per hour.
To do so, we can divide 300 by 6 to get a total of 50km/h.
