Final answer:
The correct answer to the question is C. 400 meters, because in a 400-meter run, the runners cover a total path length of 400 meters even though they start and end at the same point.
Step-by-step explanation:
The question 'If the runners of the 400 meter event start and end at the same location, what is their DISTANCE? A. 0 meters B. 200 meters C. 400 meters D. None of the above' refers to the total path or length covered by the runners during the race, regardless of the starting and ending points being the same. The correct answer is C. 400 meters.
This is because in track and field, the term 'distance' refers to the total length of the path taken by the athlete during an event. Since the event is a 400-meter run, each runner covers a total distance of 400 meters, despite ending at the same point where they started. This would be different from 'displacement', which considers the shortest path between starting and ending points and would be 0 in this scenario because the starting and ending points are the same.
