The table gives the outside temperature in degrees fahrenheit on a winter day in death valley, california. (this is the graph time) (a. m.) 7: 00 8: 00 9: 00 10: 00 11: 00 temp. (°f) 75 79 82 88 92 calculate the average rate of change in temperature between 8: 00 am and 11: 00 am. round your answer to two decimal places. a. 4.33° c. 4.64° b. 5.36° d. 3.26°

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
