You are forgetting the planet is round, once you wrap it up the three lower kingdoms are about the same distance apart, whild Vale and Mistral are about the same distance from Atlas and Vacuo is much further,

Oh, and is it not possible that Taiyang didn't train Ruby because he was training Yang to use his style of fighting? Maybe she was complete garbage at the brawling technique that dad and big sister use?
