The answer would be letter a. 4.33. The answer is derived by taking the individual temperature change rate between 8:00AM-11:00 AM.

Temperature change rate = T2-T1

T1=82-79 = 3

T2=88-82=6

T3=92-88=4

Then take the average of the three:

Average temperature rate = (T1+T2+T3) / 3

= (3+6+4) / 3

= 4.33
