Final answer:
Without the distance the second runner covered, we cannot conclusively compare Andre's speed with the second runner's speed. However, if they ran the same distance, Andre would be faster since he took less time (15 minutes) compared to the hypothetical 20 minutes of the second runner.
Step-by-step explanation:
To determine if Andre and the second runner ran at the same speed, we need to calculate the speeds using the distances and times provided. We can use the formula for speed, which is distance divided by time. For Andre, we'll divide the distance of 2 kilometers by the time of 15 minutes. For the second runner, we don't have a fixed distance, so we can't perform an actual calculation.
Although we cannot directly compare Andre's speed with the second runner's speed without knowing the distance the second runner covered, we can analyze the information given. If we assume the second runner ran the same distance as Andre, which is 2 km in a longer time of 20 minutes, we can compare the speeds. Since speed is distance divided by time, the runner with the shorter time for the same distance is faster. Therefore, Andre, who ran 2 km in 15 minutes, would have a higher speed compared to someone who ran the same distance in 20 minutes.
However, without the second runner's distance, we cannot conclusively say whether the speeds were the same or different. Additionally, considering the statement about average speed of runners from the information provided, this won't directly help in comparing Andre and the second runner's speeds without knowing the specific distances.
