Question

The angle between two cities is 30 degrees 15 minutes and 10 seconds. How many miles apart are they?

Answer 1

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.
