A plane leaves an airport p(10°S,60°E) and flies due north 800km/he by taking R 6370 and I 22\7 find it's position after 2hrs to the nearest degree
I don't know what "R 6370 and I 22\7" means, but each degree of latitude is 111.12 km, so going 800 km due north moves 7.2°
so he winds up at (2.8°S,60°E)
