One degree of longitude on the equator is equal to a distance of:
One degree of longitude on the equator is equal to a distance of:
(A) 96 km
(B) 80 km
(C) 55 km
(D) 112 km
At the Equator, the distance covered by one degree of longitude is about 111-112 kilometers. Because the Earth is widest at the Equator. Its circumference is about 40,075 kilometers. A circle is 360 degrees.
So the distance covered by one degree at the Equator will be:40,075 km ÷ 360 ≈ 111.3 km
In Geography or exam contexts, we often approximate this to 112 km.
