Answer:
The average speed for the entire run is 12 km/h.
Explanation:
The average speed is given by the following equation:
Where:
: is the total distance
: is the total time
If during the first hour, they ran a total of 13 kilometers and then, they ran 5.0 kilometers during the next half an hour we have:
Hence, the average speed is:
Therefore, the average speed for the entire run is 12 km/h.
I hope it helps you!
