For this case what we must do is find the speed of Esmeralda.

For this, we look for the rate of  change of the function

We have then:

[tex]AVR=\frac{y2-y1}{x2-x1}[/tex]

Substituting values:

[tex]AVR=\frac{47-12}{9-2}[/tex]

Rewriting:

[tex]AVR=\frac{35}{7}[/tex]

[tex] AVR = 5 [/tex]

Answer:

Esmeralda's average rate during her trip is 5 miles per hour.
