A graph of Runner Velocity vs. Time has a horizontal axis labeled Time (s) and a vertical axis labeled Velocity $(\mathrm{m} / \mathrm{s})$, Straight lines connect adjacent points, which have approximate values as follows. $(0,0),(2,6),(4,12),(6,12),(8,12)$, and $(10,12)$
(d) What is his time (in s) for the race?
Answer
The time for the race is \(\boxed{10}\) seconds.
Step 1 ：A graph of Runner Velocity vs. Time has a horizontal axis labeled Time (s) and a vertical axis labeled Velocity (m/s). Straight lines connect adjacent points, which have approximate values as follows: (0,0), (2,6), (4,12), (6,12), (8,12), and (10,12).
Step 2 ：The time for the race can be determined by looking at the last point on the graph. The x-coordinate of this point represents the total time taken for the race.
Step 3 ：The time for the race is \(\boxed{10}\) seconds.
