Answer choice 3 (6 2/3miles) is the best one in this case.

#### Explanation:

Based on the trend of the graph, it increases at a rate of about 2 miles per 18 minutes.
Proportionally, to find the best result for 60 minutes, an equation could be set up as:
$\frac{2}{18}$ = $\frac{x}{60}$

Then using cross multiplication, the result would be:
$120$ = $18 x$

Next divide both sides by 18 to find the solution for x (the approximate number of miles):
$\frac{120}{18}$ = $6.66666666667$ or $6 \frac{2}{3}$
x = $6 \frac{2}{3}$ miles
