Final answer:
Jill runs at a rate of 7.25 miles per hour. To calculate the distance she could run in 3 hours, multiply her rate by 3, resulting in 21.75 miles.
Step-by-step explanation:
The question is asking how far Jill could run given a certain pace that she maintains. If Jill runs 14.5 miles in 2 hours, we can find her running rate by dividing the distance by time, which gives us 14.5 miles / 2 hours = 7.25 miles per hour. To find out how far she could run in 3 hours, we must assume the student meant to ask for a specific time, for example, 3 hours. We multiply her running rate by 3 hours to get the distance: 7.25 miles/hour * 3 hours = 21.75 miles. Therefore, Jill could run 21.75 miles in 3 hours at this rate.
