Chapter 8, Problem 26SGR

To determine

To Find: The constant rate of change.

Answer to Problem 26SGR

  $2^{°}F/h$

Explanation of Solution

Given: The temperature one day is shown.

  

The first two data from the graph is $(0,62),(1,64)$

Then

  $\text{Rate of change =}\frac{\text{change in temperature }}{\text{time}}$

i.e.

  $\text{Rate of change =}\frac{64-62}{1-0}=2$

Hence the rate of change is $2^{°}F/h$
