The Earth's circumference at the equator is approximately 40,075 km, and the distance between two degrees of longitude decreases as one moves away from the equator. At the latitude of Bismarck, North Dakota (approximately 47 degrees north), the distance between two degrees of longitude is approximately 111 km, while at the latitude of Austin, Texas (approximately 30 degrees north), the distance between two degrees of longitude is approximately 130 km. Therefore, traveling 2 degrees east from Austin, Texas would cover a greater distance than traveling 2 degrees east from Bismarck, North Dakota.
