On a winter day, the temperature changes by – 12.6°F in 2 h. What rational number represents the average change in the
temperature each hour?
The total change in the temperature is – 12.6°F.
The amount of time is 2 or 2.25, h.
- 12.6 = 2.25 = -5.6
The number -5.6 represents the average hourly temperature change.
Explain how to use the Example to find the quotient of -12.6 and -2.25.
