What is the equivalent distance of 1 minute of latitude?

• A. 1 statute mile
• B. 1 nautical mile
• C. 1 kilometer
• D. 1 international mile

Answer: (B)

One minute of latitude is defined as one-sixtieth of a degree of latitude. Since the Earth is approximately a sphere, the distance represented by one minute of latitude remains relatively consistent at approximately 1 nautical mile. A nautical mile is based on the circumference of the Earth and is equal to one minute of arc along any meridian. This is why the correct choice is one nautical mile. The other options do not hold this equivalency. A statute mile is used on land and is slightly shorter than a nautical mile. The kilometer is a metric unit of measurement that does not correspond directly to the navigation systems used at sea. The term "international mile" is not commonly recognized in either nautical or aviation contexts and does not have a standardized definition in this context. Therefore, the connection between minutes of latitude and nautical miles is crucial for navigation and is the reason why that answer is accurate.
