One day at 3:00 a.m., the temperature was -13 degrees F in kodiak, Alaska. At 10:00 a.m., the temperature was 22 degrees F. Whta was the average change in temperature per hour?
every hour the average of the temperature going up is 5 degrees F... the difference of 3 am and 10 am is 7 hours... 22--13 is 35.. divided by 7 the answer is 5
If you find the difference between the times and temperatures, you find there is a 7-hour difference and a 35-degree difference. If you divide 7 by 7, you get one hour, so you divide 35 by 7 to get 5. Every hour, it gets 5 degrees warmer.
