One minute arc of the great circle passing through two points
One minute arc of the longitude
1855.109 m
All the above
Answer is Right!
Answer is Wrong!
The correct answer is D. All the above.
A nautical mile is a unit of length used in navigation. It is defined as one minute of arc of a great circle of the Earth, which is the distance that a ship travels in one minute of time at a speed of one nautical mile per hour. This is
equivalent to 1.852 kilometers or 6,076.115 feet.A nautical mile is also equal to one minute of arc of the longitude, which is the distance from the equator to a point on the Earth’s surface measured along a line of longitude. This is because the Earth is a sphere, and all great circles on a sphere have the same circumference.
Therefore, a nautical mile is both one minute arc of the great circle passing through two points and one minute arc of the longitude.
