Golf Cart Race: Catch-Up Time


Donald is standing near the ${9}^{th}$ hole, waiting for his friend Chris to return with the golf cart. Chris is in such a hurry to get to the next hole that he does not slow down as he passes Donald. The graph below shows the velocity vs. time graph for both Donald and Chris, as Donald tries to catch up to the cart. Chris passes Donald at $t=0\ \text{s}$.
