The flag of the United Nations consists of a polar map of the world, with the North Pole as its center, extending to approximately 45∘45^\circ South Latitude. The parallels of latitude are concentric circles with radii proportional to their co-latitudes. Australia is near the periphery of the map and is intersected by the parallel of latitude 30∘30^\circ S.In the very close vicinity of this parallel how much are East and West distances exaggerated as compared to North and South distances?
