At 3:00 am, the temperature was - 13 degrees. in alaska. At 10:00 am, the temperature was 22 degrees, what was the average change in temperature per hour?

If you go from - 13 to 0, you have an increase of 13 degrees. Then if you go from 0 to 22 you have an increase of 22 degrees. 13 + 22 = 35.

3:00 am to 10:00 am is 7 hours so:

35 degrees/7 hours = 5 degrees/hour

Also english is my second langauge so sorry if it's hard to understand

So, there is a 7 hour span. There is 35 degree change total. So solve. Take 37/7=5

5 is the average
