Answer:
10 miles per hour.
Step-by-step explanation:
Let x represent athlete's walking speed.
We have been given that her jogging rate is 5 mph faster than her walking rate, so athlete's jogging speed would be miles per hour.
10 minutes = 1/6 hour.
20 minutes = 1/3 hour
While walking, we will get
While jogging, we will get

Therefore, athlete's walking speed is 5 miles per hour.
Jogging speed:
Therefore, athlete's jogging speed is 10 miles per hour.
