Two ants, Xavier and Yvonne, move from point a to point b on the figure below. Xavier takes path X; Yvonne takes path Y. Even though their paths are different, they both arrive at point b at the same time. Using a ruler and the fact that it took both of them 4.93 seconds to go from point a to point b, calculate both the speed and the velocity (in cm/s) for both Xavier and Yvonne and enter these values into the table. Then, in words, tell me: how do their speeds compare? How do their velocities compare?
