The temperature drops a total of 12 degrees in that time. On average, how much does the temperature change per minute?(B)Jack turns on the air conditioning in his room for 12 minutes. The temperature drops a total of 8 degrees in that time. On average, how much does the temperature change per minute?
Q. In which story could you use the quotient −12÷8 to answer the question?Choices:(A)Jack turns on the air conditioning in his room for 8 minutes. The temperature drops a total of 12 degrees in that time. On average, how much does the temperature change per minute?(B)Jack turns on the air conditioning in his room for 12 minutes. The temperature drops a total of 8 degrees in that time. On average, how much does the temperature change per minute?
Understand the problem: Step 1: Understand the problem and identify the correct story.We need to find where the quotient −12÷8 fits. This quotient represents a rate of change per unit. In story (A), the temperature drops 12 degrees over 8 minutes, so we calculate the average change per minute.
Calculate the quotient: Step 2: Calculate the quotient for story (A).−12÷8=−1.5This means the temperature drops by −1.5 degrees per minute.
Check calculation: Step 3: Check if the calculation matches the story context.Since we are looking for a rate of temperature change per minute and we calculated −1.5 degrees per minute, this matches the context of story (A).
