Tokyo, Japan and Tehran, Iran, lie on a latitude of 38 47' 00" and longitude of 141 2' 00" East and 52 5' 00" East, respectively. What is the length of the line of constant latitude between these two cities? Answer in miles.
I have tried nearly everything to answer this problem. I have used all the Great Circle Equations, the Haversine Function, etc..., and always seem to be about 30 miles short of the answer, which is supposed to be 4.79*10^3. For the problem set I am doing, that is an unacceptable error. Please tell me what I am doing wrong. Thank you!
