The correct return heading for Leg 1, which is at 29 degrees for 50 paces, is determined by finding the reciprocal of the original course heading. The reciprocal is calculated by adding 180 degrees to the initial heading. In this case, adding 180 degrees to 29 degrees results in a heading of 209 degrees. This angle points in the exact opposite direction, allowing for a return route to the starting point.
The distance for Leg 1 remains 50 paces, as the inquiry only pertains to the direction and not the distance covered. Therefore, the appropriate return heading is 209 degrees for 50 paces, confirming that the ideal choice aligns with heading back the same distance traveled initially on that leg.
The other options do not correctly reflect the necessary reciprocal heading or distance for the return leg, failing to adhere to the fundamental principles of navigation and course correction used in Search and Rescue missions.
