Question

If the temperature in city of Hawthorne dropped from 96°F at 2 PM to 78°F at 8 PM what is the average rate of change in the temperature?

Estimate the temperature at 12 PM

Answer 1

66 degrees

Explanation:

First find the difference between the two values 96 and 78. 2 pm go 8 pm is 6 hours. There is a 18 degree change between 2pm and 8 pm. 18/6 = 3. So the rate of change is 3 or -3 every hour

78 degrees at 8 pm. 4 more hours till 12pm. -3 change per hour

4x-3 = -12

78+-12 = 66
