Which term describes the unit of distance that represents approximately 1.15 statute miles?

The term that represents a unit of distance approximately equal to 1.15 statute miles is the nautical mile. A nautical mile is defined as the distance corresponding to one minute of latitude and is used primarily in marine and air navigation. This measurement takes into account the Earth's curvature, making it particularly useful for navigation over large distances where the distortions caused by projecting the spherical Earth onto a flat surface become significant.

In contrast, a fathom is a unit of measurement primarily used to denote water depth, equaling 6 feet. The chain locker refers to a storage area on a ship for the anchor chain and does not pertain to distance measurement. A marlinspike is a tool used in rope work and seafaring, mainly for untying knots or splicing ropes, and is unrelated to the concept of distance. Thus, the nautical mile is the correct term for representing a distance of approximately 1.15 statute miles in navigation contexts.
