Which question would the equation b = - 12/3 help to answer?

B

Step-by-step explanation:

The mistake is in the first line when it says over 3 hours. Meaning the 12 is broken up into each hour. So division would be the normal thing to do. In C you would multiply and in A 12 isnt negative

B. The temperature dropped 12 degrees over 3 hours. How much did it change each hour?

Step-by-step explanation:

This question is basically asking for basic math terms, to solve, you need to find the correct term that fits -12 divided by 3.

Look at A., it asks how much did the temperature change, this would be incorrect because this indicates 12 - 3. Subtraction, not division, it needs to mention splitting equally.

Now B, it asks how much did the temperature change each hour, this is correct because it indicates a split evenly within the temperature change.

C is incorrect because it asks how much did it change in total, which indicates adding, not divison

Therefore B is correct.
