One mile per minute
"A nautical mile is a unit of distance used in navigation and aviation.
Originally, a nautical mile was defined as the length of an arc of a great circle on the surface of the Earth, equal to one angular minute. Thus, moving one nautical mile along a meridian corresponds approximately to a change in geographical coordinates of one minute of latitude."
