The correct answer is: A person running on a treadmill at 3 mph for 6 minutes.
Explanation: In this situation, the distance traveled is directly proportional to time because the person is running at a constant speed of 3 mph. This means that every hour, they will cover the same distance, and in any shorter amount of time, the distance they travel can be calculated by multiplying their speed by the time. The other options involve varying speeds or changes in direction, which do not consistently produce a direct proportionality between distance and time.
