Dances runs around a track in sixty seconds. Wolves, running in the opposite direction around the track, meets Dances every twenty seconds. How long does it take for Wolves to run around the track?
-Problem modified from UNL Math Day
dances takes 60sec to run around the track. when he meets the wolves the first time in 20sec, he is 1/3 around the track. since the wolves are coming in the other direction they are actually the other 2/3 around the track. whick means the wolves are travelling twice as fast as dances and they get around the track in 30sec
