Geographical coordinates map with labeled locations and coordinate lines.

To solve the problem of finding the geographical coordinates of the marked places on the map, we need to identify their latitude and longitude. Let's go through each point step by step:

Key Elements of the Map:

1. Latitude Lines: These are horizontal lines that run parallel to the Equator. The Equator is at 0° latitude.
- North of the Equator: Positive degrees (e.g., 30°N, 45°N).
- South of the Equator: Negative degrees (e.g., 30°S, 45°S).

2. Longitude Lines: These are vertical lines that run perpendicular to the Equator. The Prime Meridian is at 0° longitude.
- East of the Prime Meridian: Positive degrees (e.g., 30°E, 45°E).
- West of the Prime Meridian: Negative degrees (e.g., 30°W, 45°W).

Identifying Coordinates for Each Point:

#### Point A
- Latitude: Point A is located just north of the Equator, approximately at 15°N.
- Longitude: Point A is on the Prime Meridian, which is 0° longitude.
- Coordinates: \( (15°N, 0°) \)

#### Point B
- Latitude: Point B is located in the northern hemisphere, approximately at 60°N.
- Longitude: Point B is west of the Prime Meridian, approximately at 90°W.
- Coordinates: \( (60°N, 90°W) \)

#### Point C
- Latitude: Point C is located in the northern hemisphere, approximately at 60°N.
- Longitude: Point C is east of the Prime Meridian, approximately at 90°E.
- Coordinates: \( (60°N, 90°E) \)

#### Point D
- Latitude: Point D is located in the southern hemisphere, approximately at 30°S.
- Longitude: Point D is west of the Prime Meridian, approximately at 75°W.
- Coordinates: \( (30°S, 75°W) \)

#### Point E
- Latitude: Point E is located in the southern hemisphere, approximately at 15°S.
- Longitude: Point E is east of the Prime Meridian, approximately at 90°E.
- Coordinates: \( (15°S, 90°E) \)

#### Point F
- Latitude: Point F is located in the southern hemisphere, approximately at 60°S.
- Longitude: Point F is west of the Prime Meridian, approximately at 90°W.
- Coordinates: \( (60°S, 90°W) \)

#### Point G
- Latitude: Point G is located in the southern hemisphere, approximately at 60°S.
- Longitude: Point G is east of the Prime Meridian, approximately at 90°E.
- Coordinates: \( (60°S, 90°E) \)

#### Point H
- Latitude: Point H is located in the northern hemisphere, approximately at 75°N.
- Longitude: Point H is west of the Prime Meridian, approximately at 180°W (or equivalently, 180°E).
- Coordinates: \( (75°N, 180°W) \)

#### Point J
- Latitude: Point J is located on the Equator, which is 0° latitude.
- Longitude: Point J is east of the Prime Meridian, approximately at 30°E.
- Coordinates: \( (0°, 30°E) \)

#### Point K
- Latitude: Point K is located on the Equator, which is 0° latitude.
- Longitude: Point K is west of the Prime Meridian, approximately at 30°W.
- Coordinates: \( (0°, 30°W) \)

Final Answer:

\[
