To find the constant rate of change of the temperature, we need to determine the change in temperature divided by the change in time.

The initial temperature at noon was 88°F, and by 4 P.M., the temperature was 72°F. The change in temperature is 72°F - 88°F = -16°F (a decrease of 16 degrees).

The time difference between noon and 4 P.M. is 4 hours.

To find the constant rate of change, we divide the change in temperature by the change in t...
