How does pacing assist in navigation?

Pacing is a fundamental technique in navigation that allows individuals to estimate distances traveled on foot. By knowing how many steps it takes to cover a set distance, a person can then calculate the total distance covered based on the number of paces taken. This method is particularly useful in situations where maps or GPS devices may not be available or practical to use. By estimating distance accurately, a navigator can better assess their position and plan their route, making pacing an essential skill in both land navigation and outdoor activities.

The other options address different aspects of navigation but do not specifically focus on the primary function of pacing. While keeping track of speed can be important, pacing is more directly tied to estimating distance rather than speed. Visual references may aid in navigation by providing landmarks or points of orientation, but they do not relate directly to the concept of pacing itself. Measuring terrain elevation is also a different facet of navigation that involves understanding the vertical aspects of the landscape, rather than the horizontal distance covered through pacing.
