Given:

The temperature change was reported to be -54.5 degrees in 2.8 hours.

To find: The average change in temperature per hour

Step-by-step explanation:

The average change in temperature is,

`\begin{gathered} Average\text{ change}=\frac{|Change\text{ }in\text{ }temperature|}{Time} \\ =(|-54.5|)/(2.8) \\ =19.4 \\ \approx19^(\circ)\text{ per hour} \end{gathered}`
