To determine which runner finishes in second place, let's analyze the information provided for each runner based on their starting positions and the times taken to reach the finish line:
- Runner A: Starts at 0 meters and reaches 10 meters in 10 seconds.
- Runner B: Starts at 0 meters and reaches 10 meters in 2 seconds.
- Runner C: Starts at 1 meter and reaches 10 meters in 4.5 seconds. To find how long it takes Runner C to reach the finish line from the start:
- Distance from the starting point (1 meter) to the finish line (10 meters) is \(10 - 1 = 9\) meters.
- The time taken to run 9 meters is 4.5 seconds.
- To find the speed, we can use speed = distance/time = \(9 \text{ meters} / 4.5 \text{ seconds} = 2 \text{ m/s}\).
- Runner D: Starts at 5 meters. If we assume Runner D needs to reach the 10-meter mark, they have to cover a distance of \(10 - 5 = 5\) meters. However, we don’t have specific timing for Runner D, so we'll have to infer.
From this analysis:
- Runner B finishes in 2 seconds.
- Runner C finishes in 4.5 seconds.
- Runner A finishes in 10 seconds.
We don’t have exact timing for Runner D, but they have a starting disadvantage at 5 meters. Therefore, it’s reasonable to assume Runner D takes longer than Runner A if they are running a similar pace.
Given the information available:
- Runner B finishes first in 2 seconds.
- Runner C finishes second in 4.5 seconds.
Therefore, Runner C finishes in second place.
