The required rearranged equation is
![t=(d)/(r)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/jceg2f6dj4vdrpghdytqe3kexkzkla32bm.png)
SOLUTION:
Given, Brian is riding his bike.
He biked a distance of 14 miles at a rate of 14 miles per hour.
We have to rearrange the distance formula, d = rt, to solve for Brian's time in minutes.
Now, we have to calculate time so, the equation will be rearranged as
![t=(d)/(r)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/jceg2f6dj4vdrpghdytqe3kexkzkla32bm.png)
Here, d is distance = 14 miles and r is rate of speed = 14 miles per hour
Then,
![\text { time } \mathrm{t}=\frac{14 \text { miles }}{14 \text { miles per hour }}=(14)/(14)=1 \text { hour }](https://img.qammunity.org/2020/formulas/mathematics/middle-school/2ca9k6v3ont0xmyfjamdjp3wafm3g6lxty.png)
