Final answer:
The average rate of change in temperature per hour during the snowstorm is -5°F.
Step-by-step explanation:
To determine the average rate of change in temperature per hour, we need to calculate the difference in temperature and divide it by the time elapsed.
In this case, the temperature drops from 0°F to -10°F, which is a decrease of 10°F. The time elapsed is 2 hours.
Therefore, the average rate of change is: (-10°F - 0°F) / 2 hours = -10°F / 2 hours = -5°F per hour.
So, the correct answer is A. -5°F.
