Determine the approximate latitude and longitude of Shoshone County Airport.

• A. 47°33'N-116°11'W
• B. 36°24'N-76°01'W
• C. 47°21'N-101°01'W
• D. 47°33'N-116°11'E

Answer: (A)

Latitude and longitude tell you where a place sits by how far north or south it is from the equator and how far west or east it is from the prime meridian. Shoshone County is in northern Idaho, so its airport sits around 47.5 degrees north and about 116.2 degrees west. The coordinate pair 47°33'N-116°11'W matches that location exactly: 47°33' is 47.55°, and 116°11'W is about 116.18° west. The other options place you in different parts of the country or use the wrong hemisphere for longitude, so they don’t fit northern Idaho.
