ANSWER
5°F/hr
EXPLANATION
At 3 a.m., the temperature was -13°F and at 10 a.m., the temperature was 22°F.
To find the average change in temperature per hour, we first have to find the number of hours between 3 a.m. ad 10 a.m.
There are 7 hours between 3 a.m. and 10 a.m.
Then, find the change in temperature by subtracting the initial temperature from the final temperature:
[tex]\begin{gathered} \mleft\lbrace22-(-13)\}\degree F\mright? \\ \mleft\lbrace22+13\}\degree F\mright? \\ 35\degree F \end{gathered}[/tex]Finally, find the average change in temperature per hour by dividing the change in temperature by the number of hours:
[tex]\begin{gathered} \text{Average Change per hour = }\frac{35}{7} \\ \text{ACph}=5\degree F\text{/hr} \end{gathered}[/tex]That is the answer.
