The average distance depends on the amount of visibility.

The average person can see around 10 million different colors.
The average speed of a person is calculated by dividing the total distance covered by the total time taken. Mathematically, it is represented as Average Speed = Total Distance / Total Time. This relationship indicates that for a given distance, as the time taken decreases, the average speed increases, and vice versa. Thus, average speed provides a measure of how quickly a person travels over a specific distance.
The distance one can see ahead, known as line of sight, depends on factors like terrain, weather conditions, and visibility. On a clear day with no obstructions, a person with average eyesight can typically see objects several miles away. However, this distance can be limited by factors such as fog, rain, or obstacles in the environment.

depends where you're moving.
I'm not an opthamologist, but I believe that 15/15 is no better nor worse than 20/20.15/15 means that at 15 feet distance from the chart, you see what the average person would see at 15 feet distance.20/20 means that at 20 feet distance from the chart, you see what the average person would see at 20 feet distance.Since some people have problems with distance vision (Myopia), and some people have problems with near vision (Hyperopia), it would seem possible for someone to have 15/15, but not 20/20, or vice versa.
Having 20/15 vision means the person can see at 20 feet what an average person can see at 15 feet, indicating better than average vision. In comparison, someone with 20/20 vision sees at 20 feet what an average person sees at 20 feet.
A person of height 1.7 metres can see a bright light at the horizon - a distance of 4.7 kilometres.
distance=speed x timeso speed = distance/time
Yes, 20/15 vision is considered better than average. In this measurement, the first number (20) indicates the distance at which a person can see clearly, while the second number (15) means that they can see at 20 feet what a person with normal vision (20/20) can see at 15 feet. This level of vision is often associated with enhanced visual acuity, allowing individuals to see finer details at a distance.
The distance between Buenos Aires and Mexico City are 7,380 kilometers (4,587 miles). The average person walks at a speed of 5 kilometers (3 miles) an hour. Without stopping, the average person would take 63 days to walk such distance.
