What is the latitude for 10s to 76w longitude?

Answer 1

Sadly, the phrase "10s to 76w longitude" is quite meaningless.

-- As soon as you say "10s" or "10 south", that's the latitude.

-- 10s/76w is the latitude and longitude of a point. The point is
in central Peru, about 165 miles northeast of the center of Lima.

Answer 2

The latitude at 10°S is 10 degrees south of the equator (0° latitude). The longitude at 76°W is 76 degrees west of the Prime Meridian (0° longitude).
