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:

AVR=\frac{y2-y1}{x2-x1}

Substituting values:

AVR=\frac{47-12}{9-2}

Rewriting:

AVR=\frac{35}{7}

AVR = 5

Answer:

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