Answer:
The rate of change in this situation is 6 degrees per hour.
Explanation:
The rate of change in this situation is -6 degrees per hour. To find this, we need to divide the change in temperature by the amount of time over which the change occurs. In this case, the temperature falls from 43 degrees to 43-6=<<43-6=37>>37 degrees, so the change in temperature is 43-37=<<43-37=6>>6 degrees. Since the temperature falls over the course of one night, the rate of change is 6 degrees / 1 night = -6 degrees per hour.
