Which method is NOT a way of estimating distance?

Estimating distance can be approached through various methods that rely on calculation, physical measures, or observational skills. The correct answer highlights that using guessing is not a reliable or systematic method for estimating distance.

Timing, pacing, and measuring with tools all involve structured techniques that can yield more accurate distance estimates. Timing can be related to speed and can be used in conjunction with known data. Pacing involves the use of one's stride length, allowing for a physical sense of distance as you walk. Measuring with tools, such as a tape measure, provides a concrete and accurate measurement of distance based on the physical dimensions of objects or space.

In contrast, guessing lacks a foundational basis or standard approach; it relies on personal intuition without any methodical application, leading to potentially unreliable estimates.
