Which three basic elements must be determined to navigate by dead reckoning?

Navigating by dead reckoning involves calculating one's current position based on a previously known location, along with other factors. The three basic elements required are a starting point, distance, and azimuth.

The starting point is crucial as it serves as the reference for calculating subsequent positions. Distance accounts for how far one has traveled from that starting point, and this can be measured in various units such as miles or nautical miles. Azimuth, which refers to the angle or direction of travel (often measured in degrees from true north), indicates the specific compass direction to follow. By continuously updating your position at intervals based on these three components, you can achieve accurate navigation through dead reckoning.

In contrast, the other options introduce elements that may play a role in navigation but are not fundamental to the specific process of dead reckoning. For instance, determining current location, intended destination, and speed may be relevant in broader navigation practices, but they do not directly encapsulate dead reckoning as it requires a focus on the starting point and directional movement. Similarly, map coordinates, travel time, and compass heading, while useful in navigating, also do not align as closely with the core mechanics of dead reckoning. Lastly, factors like time of day, wind direction, and
