30 degrees can be converted to miles as follows
1 degrees = 69 miles
30 degrees = 69 * 30 = 2070 miles
1 minutes = 1.15 miles
15 minutes = 1.15 * 15 = 17.25 miles
1 seconds = 0.0193 miles
10 seconds = 10 * 0.0193 = 0.193 miles
2070+17.25+0.193 = 2087.443 miles
Note the distance is along the latitude.
