Mariana [72]

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
