What is the velocity of a group of explorers traveling from Antarctica to Australia, traveling 1500 miles in 48.0 hours? 31.3 mph north

Answer 1

Hi Alexus R.,

Looks like you answered your own question. It's just distance divided by time, approximating the trajectory to be due north from "Antarctica" (which is pretty big, in and of itself, just sayin. But for a real hoot, look up "Restaurants near McMurdo Station" [Antarctica] -- Wow!) to "Australia". But now imagine that you are watching the Earth from space, so that the explorers are taking a spiral around the globe twice as they accomplish their latitude change. Now how far do they appear to have gone in total (and you'll need a bit more math than in the simpler case!)
