Question

A graph titled Position versus time for 3 runners with horizontal axis time (seconds) and vertical axis position (meters). A blue line labeled A has the greatest upward slope followed by an orange line labeled B followed by a green line labeled C. Lines A and B intersect 0 seconds 0 minutes while line C intersects the vertical axis at 0 seconds a positive distance above 0 meters.
Which runner had the fastest speed in the race?



Which runner had the slowest speed in the race?



Which runner had a head start?

Answer 1

From your description of the graph:

1. **Fastest Runner**: The runner with the fastest speed is represented by the line with the greatest upward slope. Since line A has the greatest upward slope, runner A had the fastest speed in the race.

2. **Slowest Runner**: The runner with the slowest speed is represented by the line with the smallest upward slope. Since line C has the least steep slope among the three runners, runner C had the slowest speed in the race.

3. **Head Start**: The runner who had a head start is the one whose line intersects the vertical axis above 0 meters at time 0 seconds. Since line C intersects the vertical axis at a positive distance above 0 meters, runner C had a head start.

To summarize:
- Fastest speed: Runner A
- Slowest speed: Runner C
- Head start: Runner C
