Answer:
1. 0 N 0 E
11. 40 N 60 E
12. 40 N 120 W
18. 24 S 30 W
17. 50 S 90 E
Step-by-step explanation:
Follow a horizontal line to the left side of the map to see the latitude north or south. In some cases (16, 17, 18, 20), interpolation is required. You have to make an estimate of the fraction of the distance the point is between lines that are 20° apart.
For the longitude, the same process is followed. Follow the longitude lines to the top of the map to the scale indicating east or west longitude. Some interpolation is required there, too.
A few examples are listed above to give you the idea.
