Jasmine is running in a race. She runs 1,500 meters in 7 minutes. She starts out fast, slows down toward the middle of the race, and then finishes by sprinting to the finish line. Choose the sketch of a graph that exhibits the qualitative features of the relationship between the number of minutes Jasmine has been running and the distance she has run.(1 point)

A coordinate plane shows the x-axis, labeled as Number of Minutes, ranging from 0 to 10 in increments of 1, and the y-axis, labeled as Number of Meters, ranging from 0 to 1600 in increments of 100. A straight line connects the following two plotted points: left parenthesis 0 comma 0 right parenthesis and left parenthesis 7 comma 1,500 right parenthesis.

A coordinate plane shows the x-axis, labeled as Number of Minutes, ranging from 0 to 10 in increments of 1, and the y-axis, labeled as Number of Meters, ranging from 0 to 1600 in increments of 100. A curve connects 2 plotted points. The coordinates of a plotted closed circle are left parenthesis 0 comma 0 right parenthesis, and a second closed circle is plotted at left parenthesis 7 comma 1500 right parenthesis. An upward concave curve connects the two points. The curve passes through left parenthesis 6 comma 800 right parenthesis.

A curve with a closed circle at both the ends is shown. The coordinates of a plotted closed circle are left parenthesis 0 comma 0 right parenthesis. An upward curve extends from this point and increases steeply to left parenthesis 4 comma 900 right parenthesis, then levels off slightly, and then increases steeply to left parenthesis 7 comma 1500 right parenthesis.

To illustrate Jasmine's running pattern in the race, we need a graph that shows her initial fast pace, a slowing down in the middle, and then a final sprint to the finish line. Based on the descriptions provided:

  1. Starting fast: This suggests a steep incline at the beginning of the graph.
  2. Slowing down in the middle: This would mean the graph flattens out, indicating a decrease in speed (less distance covered over time).
  3. Finishing with a sprint: This implies a steep increase again towards the end of the race.

The graph option that best fits this description would show a curve that starts steep, flattens out in the middle, and then steepens again towards the finish line at 1,500 meters in 7 minutes.

Among the graph options, the one that describes a curve that might pass through a point at the middle distance (like 800 meters at about 6 minutes) is most fitting. Therefore, the second choice aligns closest with this dynamic of speed and distance throughout the race.

The choice should be the one that shows the curve with an upward concavity, indicating the acceleration at the start and end while reflecting the deceleration in the middle.

Thus, the best option is: A coordinate plane with an upward concave curve connecting the two points (0, 0) and (7, 1500) and passing through (6, 800).
