Question

Over a period of 12 hours the temperature dropped 36 F. What was the average change in temperature in one hour?

Answer 1

This is a rate of change, as temperature decreases with an increase in time. Therefore, 36/12=3. So, your answer is 3 degrees per hour. This is because we must divide 36 (total) degrees into 12 equal parts (hours), to get the temperature per hour, and since 3•12=36, we know we are right.

Answer: dropped 3 degrees per hour
