You try first
You told me earlier that it was about 40,000 km around great circle. Here you call it 40,213
Then it would be 40,213 * cos (latitude) to go 360 degrees around a particular latitude.
To proceed along a particular longitude would of course be 40,213/360 km/degree
A moving object takes off from a town p(latitude 40°N ,longitude 52°E) and after flying 1450km due East,it reaches a town Q.it then flies due North to another town S on latitude 60°N.
1)Calculate the longitude Q
2)The distance Q and S along the parallel of longitude (take r=6400km ,π=3.142?

By the way I only do nautical miles for which each is one minute of longitude.
One minute around the equator that is.
