When estimating distance with elapsed time, what is important to keep in mind?

When estimating distance with elapsed time, it is essential to swim at a normal, relaxed pace. This approach allows for a more consistent and accurate gauge of both the distance covered and the time elapsed. When a diver swims too fast, fatigue can set in quickly, which may lead to variations in speed and thus distort distance estimation. A relaxed pace not only contributes to ease of movement but also helps maintain a steady rhythm, making it easier to accurately measure the time taken to cover specific distances.

Controlling for factors such as current flow or fatigue is crucial when estimating distance, and swimming at a relaxed pace can help divers account for these variables more effectively. A measured approach also helps in conserving energy, which is particularly important in an underwater environment where physical exertion can lead to rapid exhaustion and affect safety.
