Answer:

She can travel 21.75 miles in 3 hours.

Step-by-step explanation:

Firstly, you have to find out how many miles can Jill travel in 1 hour. So you divide it by 2 :

[tex]2hr = 14.5miles[/tex]

[tex]1hr \: = 14.5 \div 2 \\ 1hr = 7.25miles[/tex]

We have found out that she can travel 7.25 miles per hour. Next wr have to multiply it by 3 as the question says how far she run in 3 hours :

[tex]1hr = 7.25miles[/tex]

[tex]3hr = 7.25 \times 3 \\ 3hr = 21.75miles[/tex]
