A point is at 47°50′27″N. Which latitude is 240 NM directly north, using the 60-NM-per-degree rule?

At approximately 60 NM per degree of latitude, 240 NM corresponds to $240/60=4^\circ$. Add four degrees to the starting latitude: $47^\circ50'27''N + 4^\circ = 51^\circ50'27''N$. The minutes and seconds remain unchanged for this idealized north–south calculation.\n\n**Key takeaway:** Convert north–south distance to degrees using 60 NM per degree.\n\n**Glossary:** **Latitude**: angular position north or south of the equator.
