Question 1130051: 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.
Could you please explain the reasoning behind your answer such that I can explain to my child. This is my child's math homework who is a 6th grader.

Please note: I asked this question earlier and the tutor replied about how she has never heard temperature drop so quickly in nature!!! I did not make this question. It is straight out of my child's math textbook. As illogical as it may sound, the question is targeted at math and not weather accuracy.Would appreciate the answer please!

Answer (a) :  Expression to evaluate the average change in temperature per minute is 

              %2825+-+%28-23%29%29%2F8.



Answer (b) :  The mean change in temperature per minute is

              %2825+-+%28-23%29%29%2F8 = 6 degrees of Fahrenheit per minute.

---------------

To answer the question, you need first to evaluate the temperature difference.

It is (25 - (-23)) = 48 degree of Fahrenheit .

Then you need to divide this difference by the time of 8 minutes to get the rate of the temperature change per minute.
