5,183 miles via the shortest (great circle, north/south) route.
About 69.1 miles (111.2 km).
An average minute of latitude is a nautical mile. The difference between 68° and 66.56°, the approximate latitude of the Arctic Circle, is 1.44°, which is about 86.4 minutes, which is about 86.4 nautical miles. Multiplying by 1.15 miles per nautical mile gives you about 99.4 miles, which is about 160 kilometers.
Latitude. 2nd answer: Latitude is the wrong answer. Distance is measured in miles, feet, yards, meters, kilometers, and so forth. Latitude is a measurement of degrees, not distance.
The Earth is not a perfect sphere, and the WGS84 system that we use for degree confluences includes a mathematical model (GRS80) of the Earth as an ellipsoid. Using established GRS80 constants, and the Vincenty Algorithm (PDF document), the distance between degrees of latitude (lines that run east-west) varies from 110.57km (68.71mi) at the equator (0 degrees latitude) to 111.69km (69.40mi) between 89 degrees latitude and the poles. For the purposes of the project, we don't take these variations in the distance between degrees of latitude into account when categorizing degree confluences. Using the same calculation methods, the distance between degrees of longitude (lines that run north-south) varies between 111.32km (69.17mi) at the equator (0 degrees latitude) to 1.95km (1.21mi) at 89 degrees latitude, one degree from the north or south pole. Because the lines of longitude meet at the poles, the distance between degrees of longitude at the poles is zero.
The distance around the earth at forty degrees South Latitude would be 19,049 miles. The circumference of Earth at the equator is 24,902 miles.
I get 4,354 miles (7,007 km).
About 69.1 miles (111.2 km).
-- 164 degrees -- 11,334 miles -- 18,240 km
because the north pole is 90 degrees latitude

Earth's Circumference at the Equator: 24,901.55 miles (40,075.16 km) (from about.com); 0 degrees latitude is the equator.
Miami is about 25 degrees north. Assuming the points are in the same longitude, that's about 2421 miles.

The Prime Meridian is defined as zero degrees of longitude. The distance in miles between degrees of longitude depends on the latitude; one degree of longitude equals the cosine of the latitude * 60 nautical miles. Note: If you're using Excel or some other spreadsheet program, be sure to convert degrees into radians before calculating the cosine of the latitude.
At 37 degrees north latitude, 1 degree of longitude is approximately 53 miles. The distance varies depending on the latitude due to the Earth's curvature.
