#### Answer

All three runners finished the race
A 1st
B 2nd
C 3rd
The velocity and speed of each runner changed as they proceeded.

#### Work Step by Step

Firstly, by looking at the y-coordinates of the three points, which are the same, 100, we know that they all finished the race.
Secondly, by looking at the x-coordinate of the three points (the time), we can see it takes A less time than B and B less time than C to finish the race.
