10 20 30 40 50 60 70 80 90 100. That’s how we do it

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 isin central Peru, about 165 miles northeast of the center of Lima.
