This isn't a homework question. My friend stumbled upon his textbook that stated since the circumference of the globe is 2*pi*r, the velocity of someone who "ran all the way around" would be v = (2*pi*r)/t.(adsbygoogle = window.adsbygoogle || []).push({});

However, isn't the displacement zero? And velocity = displacement/time?

so is this a textbook typo, or is there another point I'm missing? xD
