(04.05)
The graph shows Kendra's morning run:
A graph is shown with the title Kendra's run. The x-axis is labeled Time running, and the y-axis is labeled Distance run. Segment A begins at the origin and continues upward until x equals 0.2. Segment B begins at x equals 0.2 and continues upward at a faster rate until x equals 0.75. Segment C is a horizontal line from x equals 0.75 until x equals 0.8. Segment D moves in an upward direction until x equals 1.5

Camryn ran for 13 minutes, walked for 17 minutes, ran for another 13 minutes, and then sat down and stretched in place for 17 minutes. Her total distance traveled is a function of time.
Which graph most accurately represents this scenario?
A graph is shown with a starting point at the origin. The x-axis is labeled Time (in hours), and the y-axis is labeled Total distance (in miles.) The graph moves upward, then at 0.25 hours moves up at a slower pace until it reaches 0.5, where it moves up at a fast pace again before changing to a horizontal line from 0.75 to 1
A graph is shown with a starting point at 0 comma 1.2. The axis is labeled Time (in hours) and the y-axis is labeled Total distance (in miles). The graph is horizontal until x equals 0.25 hours, then moves downward to 0.5. From 0.5 to 0.75, the graph moves upward quickly, before continuing down to touch the x axis at x equals 1
A graph is shown with a starting point at the origin. The axis is labeled Time (in hours) and the y-axis is labeled Total distance (in miles). The graph moves upward quickly until 0.25 hours, then is a horizontal line until 0.5 hours. From 0.5 to .075 hours, the graph moves upward, and from 0.75 to 1 hour, it moves upwards at a faster rate
A graph is shown with a starting point at the origin. The axis is labeled Time (in hours) and the y-axis is labeled Total distance (in miles). The graph moves upward until 0.25 hours, then is a horizontal line until 0.5 hours. From 0.5 to 0.75 hours, it moves downward slowly, and from 0.75 to 1 hour, it moves down until it touches the x=axis
