• Student Y starts out slower than Student X, and Student Y finishes second.

A toy robot moved from a starting point and traveled in a straight line at different speeds. Then the robot turned around and traveled in a straight line at different speeds as it returned to its starting point. Which sentence describes the motion of the robot between seconds 3 and 4?

• The robot was moving away from the starting point.

• The robot was moving toward the starting point.

• The robot was stopped in one place away from the starting point.

• The robot was moving back and forth around the starting point.

• Carlos won the race because he reached the finish line in a shorter amount of time.

• Andrew won the race because he reached the finish line in a longer amount of time.
