Answer:

Average change in temperature is - 2.8 Fahrenheit per hour.

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
