Expression for Change in temperature
The temperature in Brownsville fell from 25°F to −23°F in 8 minutes.
a. Write a numerical expression you can evaluate to find the average change in temperature per minute.
b. Find the mean change in temperature per minute.
This question is from my 6th graders Math textbook. Would appreciate a simple explanation that an elementary grade student can comprehend. Thanks in advance!
Edit: I found the solution elsewhere as -( 25 -(-23)) ÷ 8 . Is this correct? If so, please explain why the expression to find the change in temperature is -(25 - (-23)) ?

That's a strange way of putting it. It's simply $${-23-25over8}=-6text{ degrees per minute}$$ Change in temperature divided by the time interval.
The answer in the book is correct, but I don't understand the reason for the "double negative."

There's something fishy about Pearl deliberately posting duplicate questions here (this isn't the only one). Maybe you don't want to have an answer associated with these shenanigans.

@GerryMyerson I assume it's just because my answer on the previous one wasn't to her liking; specifically because I couldn't adequately answer her question regarding the "how to calculate the change in temperature" thing. Wasn't really able to reply because I don't really know how to phrase or explain "the change in temperature" or "final temp minus initial temp" as anything more elementary/intuitive. >_>
