Step-by-step explanation:
The airport located at approximately 47° 40' N latitude and 101° 26' W longitude is Garrison County Regional Airport. The latitude and longitude coordinates provided in the question represent the airport's location on the Earth's surface. The latitude measures how far north or south a place is from the Equator, while the longitude measures how far east or west a place is from the Prime Meridian.
Using these coordinates, we can determine that Garrison County Regional Airport is the airport closest to the specified latitude and longitude. It is near the city of Garrison in McLean County, North Dakota, United States. There is some confusion because this airport is sometimes informally referred to as Garrison County Regional Airport, but it should not be confused with other similarly named facilities. Semchenko Airport is not located at the specified latitude and longitude.
