The latitude of a city is 53.35(degrees) north. If we assume that the earth is a sphere of diameter 12750km, find the distance form the city to the nearest point on the equator, travelling along the earth's surface.
I got the answer 1889.479 km, but my book says it's actually 11872km.
Am I wrong? And if so, how do I solve the question properly?
+37146 Actually .... I only get 1/2 of that ... 5935.97 km
Pi x D = circumference then 53.35/360 times that is the arc length to the equator
