The Rule of 1 in 60 is a useful navigation principle that helps pilots estimate how many degrees they are off their intended track based on how far they have flown. When assessing one's course deviations, this rule states that for every nautical mile off track, the pilot will be off course by approximately one degree for every 60 nautical miles flown.

To apply this concept, the appropriate calculation involves determining the ratio of miles off track to miles flown, which offers a direct way to ascertain the angular deviation from the intended course. By dividing the miles off track by the miles flown and then multiplying by 60, the pilot can accurately determine the number of degrees they are off course.

This calculation directly reflects the distance and degree correlation posited by the Rule of 1 in 60, allowing pilots to reorient and correct their flight path accordingly. In contrast, the other options presented either misrepresent the relationship between distance and degrees or complicate the straightforward calculation that the Rule intends to provide.
