Question 1 refers to the following figure.
Begin skippable figure description.
The figure presents a graph titled “Marilyn’s Hike” in a coordinate plane. The horizontal axis has 4 equally spaced tick marks labeled, from left to right, 12 P.M., 1 P.M., 2 P.M., and 3 P.M., and there are vertical gridlines at those tick marks. The vertical axis is labeled “Distance from campsite, in miles,” and the numbers 0, to 2.0, in increments of 0.5, appear along the vertical axis. There are horizontal gridlines at those numbers. In the figure, a curve starts off at 12 P.M. at 0 mile, moves upward and to the right while it fluctuates, passing 1 P.M. at a distance of 1.25 miles, until it stops fluctuating at a time that is one sixth of the hour past 1 P.M. Then it moves horizontally until a time that is two thirds of the hour past 1 P.M. The curve starts moving upward and to the right, until it crosses 2 P.M. at about 1.6 miles. The curve then fluctuates down and to the right until it stops at 3 P.M. at 0 mile.
