To solve this problem, we need to read the latitude and longitude lines on the map for each lettered dot.
Step 1: Understand the Grid
*
Latitude (Horizontal Lines): The Equator is at 0°. Lines above are North (N), and lines below are South (S). The scale is marked every 15° (0°, 15°, 30°, 45°, 60°).
*
Longitude (Vertical Lines): The Prime Meridian is at 0°. Lines to the left are West (W), and lines to the right are East (E). The scale is marked every 20° (0°, 20°, 40°, 60°, etc.).
Step 2: Locate Each Point
*
Point A:
* Latitude: It is on the line labeled 15° South.
* Longitude: It is on the line labeled 60° West.
* Result: 15° S, 60° W
*
Point B:
* Latitude: It is on the line labeled 45° North.
* Longitude: It is on the line labeled 40° East.
* Result: 45° N, 40° E
*
Point C:
* Latitude: It is on the line labeled 15° South.
* Longitude: It is on the line labeled 40° East.
* Result: 15° S, 40° E
*
Point D:
* Latitude: It is on the line labeled 45° North.
* Longitude: It is on the line labeled 100° West.
* Result: 45° N, 100° W
*
Point E:
* Latitude: It is on the line labeled 30° North.
* Longitude: It is on the line labeled 140° East.
* Result: 30° N, 140° E
*
Point F:
* Latitude: It is on the line labeled 15° North.
* Longitude: It is on the line labeled 100° East.
* Result: 15° N, 100° E
*
Point G:
* Latitude: It is on the line labeled 15° North.
* Longitude: It is on the line labeled 20° West.
* Result: 15° N, 20° W
*
Point H:
* Latitude: It is on the line labeled 30° North.
* Longitude: It is on the line labeled 120° West.
* Result: 30° N, 120° W
*
Point I:
* Latitude: It is on the line labeled 15° South.
* Longitude: It is on the line labeled 160° East.
* Result: 15° S, 160° E
*
Point J:
* Latitude: It is on the line labeled 0° (The Equator).
* Longitude: It is on the line labeled 120° East.
* Result: 0°, 120° E
Final Answer:
A: 15° S, 60° W
B: 45° N, 40° E
C: 15° S, 40° E
D: 45° N, 100° W
E: 30° N, 140° E
F: 15° N, 100° E
G: 15° N, 20° W
H: 30° N, 120° W
I: 15° S, 160° E
J: 0°, 120° E
