The following table gives the outside temperature in degrees fahrenheit on a summer afternoon:

time (pm) temperature (°f)
12: 00 78
1: 00 82
3: 15 88
4: 30 93
6: 00 91

a. calculate the average rate of change between consecutive data points in the table.
b. determine the time interval(s) when the thermometer was rising the fastest, on average.

A.
For 12 - 1,
82 - 78 = 4 degrees per hour

For 1 - 3:15,
(88 - 82) / 2.25 = 2.67 degrees per hour

For 3:15 - 4:30,
(93 - 88) / 1.25 = 4 degrees per hour

For 4:30 to 6,
(91 - 93) / 1.5 = 1.33 degrees per hour

The time intervals 12 to 1 and 3:15 to 4 had the fastest rate of change

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
