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:
2/18218 = x/60x60

Then using cross multiplication, the result would be:
120120 = 18x18x

Next divide both sides by 18 to find the solution for x (the approximate number of miles):
120/1812018 = 6.666666666676.66666666667 or 6 2/3623
x = 6 2/3623 miles
