Answer :
To determine the Sarah's cycling rate, here are the steps:

[tex]86mi-44mi=42mi[/tex]2. Subtract 6 hours from 12 hours.
[tex]12hrs.-6hrs.=6hrs\text{ }[/tex]3. Divide the result in step 1 by the result in step 2.
[tex]42mi\div6hrs=\frac{7mi}{hr}[/tex]Hence, Sarah's cycling rate is 7 miles per hour.
