Answer:
The average change would be -3.36 degrees.
Explanation:
We take the overall temperature change which is -16.8 and we would just simply divide that by 5. That's all to get the temperature.
Another example would be if the temperature change was 16 over the course of 4 days. In this case we would take the overall (16) and divide that by the number of days. There would be an average of 4 degree temperature change.
