Two points M and N on the surface of the earth are given by the latitude and longitude M( latitude 50°S longitude 15°E ). N(latitude 50°S longitude 75°E). Calculate : The radius of the parallel of latitude on which M and N lies. B) the distance /MN/ measured along the parallel of latitude

Question

Two points M and N on the surface of the earth are given by the latitude and longitude M( latitude 50°S longitude 15°E ). N(latitude 50°S longitude 75°E).             Calculate : The radius of the parallel of latitude on which M and N lies.                                  B) the distance /MN/ measured along the parallel of latitude

oobleck · Answer

the two cities are 60° apart, or 1/6 the circumference at latitude 50°S

Anonymous · Answer

the radius at 60 S is Rearth * cos 60 Rearth = 6.38 * 10^6 meters so circumference at 60 S = 2 pi * 6.38 * 10^6 meter * cos 60
