The winner of the race and check whether each runner has completed the race.

Answer to Problem 12E
Runner A won the race and all the three runners finished the race.
Explanation of Solution
Given:
The graph of three runners compete in a 100-meter race
Observation:
In the given graph, the x-axis represents the time in seconds and the y-axis represents the distance in meters. It is observed from the graph that the runner A reached 100 m in 15 seconds, runner B reached about 20 seconds whereas the runner C reached the destination around 23 seconds. Therefore, the runner A won the race as the runner reached the destination in short duration.
Moreover, all the three runners A, B, and C have completed the race as they reached the destination of 100 meters.
