Answer:

55 miles per hour.

Explanation:

To determine the average speed traveled by Sophie, we find the slope of the function given from the linear table.

[tex]\begin{gathered} \text{Slope}=\frac{82.5-165}{2.5-1} \\ =-\frac{82.5}{1.5} \\ =-55 \end{gathered}[/tex]

What this means is that Sophie's distance from City A is reducing at a rate of 55 miles per hour.

Thus, the average speed that Sophie travels, is 55 miles per hour.
