Answer 1

Answers:

• A = 20° North, 20° West
• B = 40° North, 120° East
• C = 20° South, 120° West
• D = 40° South, 60° East
• E = 60° North, 40° West

==========================================================

Explanation:

The equator is the middle-most horizontal line. This is the thickest horizontal line of the group.

The prime meridian is the thickest vertical line shown at the center.

Start where those two lines cross. We call this 0 degrees North and 0 degrees East.

Then move 20 degrees west and 20 degrees north to arrive at point A.

Therefore, we can describe the absolute location of point A by saying "20° N, 20° W". Always list the north/south coordinate first (aka the latitude) before listing the east/west coordinate (longitude).

You probably have come across this type of notation before if you have worked with GPS.

------------------------

Point B is located at the absolute position of 40° N, 120° E

The 40 is from moving 2 ticks up from the center. Each tick is 20 degrees, so 2*20 = 40 degrees total north. The 120 is from 6 movements to the east, so 6*20 = 120 degrees east in total.

Like with point A, and the rest of the points as well, we always start at the center.

-------------------------

Again start at the intersection of the equator and the prime meridian.

We then move 1 tick down, to move 1*20 = 20 degrees south.

We also move 6 tickmarks west to move 6*20 = 120 degrees west.

Therefore, point C's absolute location is 20° S, 120° W

-------------------------

The same idea will play out to locate points D and E.
