Question

The temperature at 6 pm was 0f. At 10 pm the temperature was -11.2f. Write an expression that you can use to find the average change in temperature per hour during that time. Then evaluate the expression.

Answer 1

Answer:

Average change in temperature is - 2.8 Fahrenheit per hour.

Step-by-step explanation:

Average change in temperature is the change in temperature divided by the time taken for the change.

Change in temperature = (-11.2) F- 0 F

                                       = -11.2 F

Time taken for the change in temperature = 10 pm - 6 pm

                                                                       = 4 hours

Average change in temperature = Change in temperature / time taken for the change

                                                      = $\frac{-11.2}{4}$

                                                      = - 2.8 Fahrenheit per hour
