What is the approximate distance between two places if one is located on 11oN and the other on 5oS on the same longitude?

To calculate the distance between two places on the same longitude, we need to find the length of the arc of the Earth's circumference between the two latitudes. The Earth's circumference is approximately 40,000 km. Therefore, each degree of latitude represents approximately 40,000 km/360 = 111.11 km. The distance between 11°N and 5°S is equal to the sum of the distance between the equator and 11°N plus the distance between the equator and 5°S. The distance between the equator and 11°N is 11° x 111.11 km/degree = 1,222.21 km. The distance between the equator and 5°S is 5° x 111.11 km/degree = 555.55 km. Therefore, the total distance between the two places is 1,222.21 km + 555.55 km = 1,777.76 km. Therefore, the answer is closest to 1,776 km.
