Question

In January 2008, the temperature in parts of Minnesota fell from 48 degrees F to -12 degrees F over a 24-hour period. What was the average temperature change per hour?
a. -(1 1/2) degrees
b. ( 1 1/2) degrees
c. -2.5 degrees F
d. 2.5 degrees F

Answer 1

To find the average temperature change per hour, we need to divide the total temperature change by the number of hours.

The total temperature change is the difference between the initial temperature (48 degrees F) and the final temperature (-12 degrees F), which is 48 - (-12) = 60 degrees F.

The number of hours is 24 hours.

Dividing the total temperature change by the number of hours gives us 60 / 24 = 2.5 degrees F.

Therefore, the average temperature change per hour is 2.5 degrees F.

The correct answer is d. 2.5 degrees F
