Answer: 2.67 degrees per hour
Step-by-step explanation: Firstly, the time range is calculated. That is, how many hours do we have from 5:00am to 2:00pm? (Answer= 7 hours).
Secondly, we find the difference between the degrees of both hours. That is, 72 degrees minus 48 degrees. (Answer = 24 degrees).
So, an increase of 24 degrees was obtained within the 9 hour period. Thus, to obtain the temperature increase per hour, we simply divide the difference gotten from the two degrees (24 degrees) by the duration (9 hours). 24 divided by 9 equals 2.67
