(56-43)/(13)=13/13=1dg/hr

the average hourly rate of temperature change is the amount the temperature changed in 1 hour (on average).
You know that in 13 hours, the temperature changed 13 degrees. So in 1 hour, the temperature would have probably changed by 1 degree. The calculation for this is to divide the temperature difference by the time difference. I will use 24 hr time because it is easier to explain. (3pm = 15:00 in 24hr time):
(56-43) deg / (15-2) hr
13deg/13hr
1deg/hr
So the hourly rate of temperature change is 1deg/hr.
Hope that helped

You know that 2am to 3pm in the same day is 13 hours. To find the overall change, do 56-43, which is 13. 13 degrees over thirteen hours is one degree per hour.
