To determine

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

Expert Solution

Runner *A* won the race and all the three runners finished the race.

**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.
