If a bear starts running at 30 mph towards Lynn, and Lynn's adrenaline kicks in and she starts riding away at 22 mph with a 100 yard headstart, how long does it take the bear to catch Lynn.

Hmmm.  This sounds like a algebra class word question -- finally I get to use my schoolin'.  If X is the speed of the bear, and Y is the speed of Lynn, and D is the distance Lynn rides, and D+100 is the distance the bear has to run, what is the value T where X times T is 100 yards greater than Y * T?

Answer:  Roughly 24 seconds.  WOW, I thought it would have taken longer than that.  Guess you were right Lynn, not fast enough.

Todd, can you and Living Proof check my math please.
