Explanation:

Step1: Recall rate - of - change formula

The average rate of change of a quantity is given by $\frac{\text{Change in quantity}}{\text{Time interval}}$.

Step2: Analyze the first story

In the first story, the change in temperature is - 24 degrees (it drops, so negative) and the time interval is 10 minutes. The average temperature change per minute is $\frac{-24}{10}$.

Step3: Analyze the second story

In the second story, the change in temperature is - 10 degrees and the time interval is 24 minutes. The average temperature change per minute is $\frac{-10}{24}$.

Answer:

The first story.
