Halifax, Nova Scotia has a latitude of 45 N, and Buesno Aires, Argentina a latitude of 34 S. Assume that the two cities lie on the same north-south line and find the distance in kilometers between them.<\/p>\n\n\n\n
The correct answer and explanation is :<\/strong><\/mark><\/p>\n\n\n\n To find the distance between Halifax, Nova Scotia (latitude ( 45^\\circ N )) and Buenos Aires, Argentina (latitude ( 34^\\circ S )), we assume both cities lie along the same north-south line, meaning we only need to calculate the difference in latitude and convert it into a physical distance.<\/p>\n\n\n\n The Earth\u2019s circumference is approximately 40,075 km<\/strong> along the equator. However, for meridional (north-south) distances, we use the meridional circumference<\/strong> of the Earth, which is about 40,008 km<\/strong> (since Earth is slightly oblate).<\/p>\n\n\n\n The length of one degree of latitude is: Thus, the total distance between Halifax and Buenos Aires is: The approximate north-south distance between Halifax, Nova Scotia, and Buenos Aires, Argentina, is 8,782 kilometers<\/strong>. This calculation assumes a perfectly spherical Earth, and actual distances may vary slightly due to Earth’s shape and terrain variations.<\/p>\n","protected":false},"excerpt":{"rendered":" Halifax, Nova Scotia has a latitude of 45 N, and Buesno Aires, Argentina a latitude of 34 S.
