Answer:
The average change in temperature per hour was -8°F.
Explanation:
Using the equation 48-(-16) we know that the temperature dropped by 64°F.
![48-(-16)=64](https://img.qammunity.org/2023/formulas/mathematics/middle-school/ws88e0qausakad482llo2qfdvzxconq1rb.png)
We now know that the temperature dropped by 64°F in a period of 8 hours. Using the equation -64/8 we can find the average change in temperature per hour.
![(-64)/(8) = -8](https://img.qammunity.org/2023/formulas/mathematics/middle-school/sn87eifucsmwzigd90g9ke5la2h76sn3tp.png)
Therefore, the average change in temperature per hour was -8°F.
