#### Answer:

#### Explanation:

I wouldn't necessarily call this a chemistry-related question, but it doesn't matter, I'll help.

The average rate of change of temperature with respect to time in this case can be represented by the equation

where

and

The total change in temperature over the time period is

and the total time change is

Plugging values into the equation, we have
