How Many Nautical Miles

A very wise but good natured mathematician once whispered to me some helpful words of advice when sailing the seven seas it takes 1,852 metres and 6,076 feet to find each nautical miles How she did it I found very shocking because I didn't even know the method she had used whether finding the circumference of the Earth surface or speed up time by sixty seconds or even plotting the gradient and a straight line I found the whole thing so confusing even for a person who is a very talented mariner but at the end all she did was as tell me that's just life my dear friend
