One day at 3:00 a.m., the temperature was
–
13
°
F
in Kodiak, Alaska. At 10:00 a.m., the temperature was 22°F. What was the average change in temperature per hour?
To find the average change in temperature per hour, we need to first find the total change in temperature and then divide by the number of hours.
Total change in temperature = final temperature - initial temperature
Total change in temperature = 22°F - (-13°F)
Total change in temperature = 35°F
Number of hours = 10 - 3
Number of hours = 7
Average change in temperature per hour = Total change in temperature / Number of hours
Average change in temperature per hour = 35°F / 7 hours
Average change in temperature per hour = 5°F/hour
Therefore, the average change in temperature per hour is 5°F.
