Using it's concept, the rate of change in temperature was of -17 ºF per minute.
What is the average rate of change of a function?
The average rate of change of a function is given by the change in the output divided by the change in the input. Hence, over an interval [a,b], the rate is given as follows:
[tex]r = \frac{f(b) - f(a)}{b - a}[/tex]
In this problem, we have that:
- The change in the output was of -25.5 ºF.
- The change in the input was of 1.5 minutes.
Hence:
r = -25.5/1.5 = -17 ºF per minute.
The rate of change in temperature was of -17 ºF per minute.
