Solution: Distances over land are measured in statute miles (5280 ft), but distances over water are measured in nautical miles, where 1 nautical mile was originally defined as 1 minute of arc along an Earth meridian, or 1/21600 of the Earths circumference through the poles. A ships speed through the water is measured in knots, where 1 knot = 1 nautical mile per hour. Historically, the unit knot derived from the practice of measuring a ships speed by throwing a log tied to a knotted line over the side. The line had a knot tied in it at intervals of 47 ft. 3 in., and the number of knots run out in 28 seconds was counted to determine speed.How many feet are in a nautical mile?
