Let's solve this step-by-step using the map and the given coordinates. The goal is to determine which U.S. state each coordinate pair falls within.
We'll use the
latitude (N/S) and
longitude (W/E) lines on the map to locate each point.
---
Step 1: Understand the Coordinate System
-
Latitude (North/South): Lines run horizontally.
- North (N) increases from south to north.
- The map shows latitudes from 25°N to 45°N.
-
Longitude (East/West): Lines run vertically.
- West (W) decreases from east to west.
- The map shows longitudes from 70°W to 125°W.
We will find where each coordinate intersects on the map and identify the state.

Now, let's go through each coordinate:
---
#### 1)
27°N, 85°W
-
Latitude: 27°N — This is near the southern part of the U.S., just above Florida.
-
Longitude: 85°W — This runs through the eastern part of the U.S., passing through Florida and Alabama.
- Intersection: This point lies in
Florida.
✔ Answer: Florida
---
#### 2)
40°N, 90°W
-
Latitude: 40°N — This line passes through the northern midwest (e.g., Illinois, Iowa).
-
Longitude: 90°W — This runs through central Illinois and Missouri.
- Intersection: At 40°N and 90°W, we are in
Illinois.
✔ Answer: Illinois
---
#### 3)
45°N, 100°W
-
Latitude: 45°N — This is near the northern border of the U.S. (e.g., Minnesota, Wisconsin, Michigan).
-
Longitude: 100°W — This runs through the center of the U.S., passing through South Dakota and Nebraska.
- Intersection: At 45°N and 100°W → This is in
South Dakota.
✔ Answer: South Dakota
---
#### 4)
31°N, 105°W
-
Latitude: 31°N — This is in the southern U.S. (Texas, New Mexico).
-
Longitude: 105°W — This line runs through western Texas and eastern New Mexico.
- Intersection: This point is in
New Mexico.
✔ Answer: New Mexico
---
#### 5)
40°N, 105°W
-
Latitude: 40°N — Midwestern/northern U.S.
-
Longitude: 105°W — Runs through Colorado.
- Intersection: This is in
Colorado.
✔ Answer: Colorado
---
#### 6)
45°N, 120°W
-
Latitude: 45°N — Northern U.S. (like Washington, Oregon, Idaho).
-
Longitude: 120°W — This line runs through the Pacific Northwest, specifically
Oregon and
Idaho.
- But at 45°N and 120°W, it’s in
Oregon (the coast is around 124°W, but 120°W is still within Oregon).
✔ Answer: Oregon
---
✔ Final Answers:
1)
Florida
2)
Illinois
3)
South Dakota
4)
New Mexico
5)
Colorado
6)
Oregon
