Answer:
1.2 degree Fahrenheit per minute.
Step-by-step explanation:
We are supposed to find the unit rate for 15.6°F in 13 minutes.
To find the unit rate for our given scenario, we will divide 15.6 by 13 as:
[tex]\text{Unit rate}=\frac{15.6^{\circ}F}{13\text{ min}}[/tex]
[tex]\text{Unit rate}=\frac{1.2^{\circ}F}{\text{ min}}[/tex]
Therefore, our required unit rate would be 1.2 degree Fahrenheit per minute.
