2. To find the distance between two points on the earth when their latitude and longitude are known, we can use a right triangle for an excellent approximation if the points are not too far apart. Point A is at 380 27' 30" N, longitude 820 57' 15" W: and point B is at latitude 380 28' 45" N, longitude 820 56' 30" W. Find the distance from A to B in nautical miles. (One minuet of latitude is one nautical mile.)
