Final answer:
One degree equals 60 nautical miles, as a degree is divided into 60 minutes of arc, and each minute of arc corresponds to one nautical mile.
Step-by-step explanation:
When we are talking about degrees and minutes in the context of angles, the question is referring to the units used to measure angles. One degree is divided into 60 minutes of arc, so if 1 minute equals 1 nautical mile (NM), then 1 degree equals 60 nautical miles. This is a standard way to convert nautical measurements used in navigation and can be important for calculating distances and bearings on a spherical surface like Earth.
