Final answer:
The temperature fell by 4 degrees per hour over the course of 6 hours.
Step-by-step explanation:
If the temperature fell by 24 degrees in a span of 6 hours, to find out how many degrees the temperature fell every hour, you divide the total temperature drop by the total time in hours. This can be represented by the following equation:
Temperature drop per hour = Total temperature drop ÷ Total time
Putting in the values from the question, we get:
Temperature drop per hour = 24° ÷ 6 hours = 4 degrees per hour.
So, the temperature fell by 4 degrees every hour during those 6 hours.
