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.
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.
Therefore, the average change in temperature per hour was -8°F.
