To find the average speed of the runner, we need to divide the total distance traveled by the total time taken. In this case, the runner jogs 12 km north and then runs 16 km east.
Total distance traveled = 12 km north + 16 km east = 28 km
Now, we need to find the total time taken by the runner. According to the information provided, it took the runner 3 hours to complete the jog.
Total time taken = 3 hours
To find the average speed, divide the total distance by the total time:
Average speed = Total distance traveled / Total time taken
= 28 km / 3 hours
= 9.33 km/h
Therefore, the average speed of the runner is 9.33 km/h.
