Why nautical mile is needed?
a nautical mile is a minute (1/60th) of one degree of the earths surface so it corresponds to maps
Why is it that 6080 ft is equal to nautical mile?
A nautical mile is the length that represents one minute of arc (1/60 degrees) along any latitude or one minute of arc of longitude along the equator. Unfortunately, the earth is not a perfect sphere so the two measures are different. By international agreement, it has been set at 1,852 metres exactly - which is about 6076 feet (not 6080).
How many minutes are equal to 1.5 miles?
1 Nautical mile is 1 minute of latitude. Therefore 1.5 nautical miles is 1'30" (1 minute 30 seconds)
What distance is represented by one minute of latitued 60 minutes for each degree?
One minute of latitude represents 1 nautical mile
Is one mile on land different than one mile in water?
A2. YES. A nautical mile is exactly 1852m which is approx 6076 feet.[It was defined as a 1 minute of arc at the Equator, and this used to be considered 6080 feet, but a re-determination of the length round the equator gives us the lower number.]A land (Statute) mile is 5280 feet.
