1. The problem statement, all variables and given/known data Cars A and B are racing each other along the same straight road in the following manner: Car A has a head start and is a distance Da beyond the starting line at t=0. The starting line is at x=0. Car A travels at a constant speed Va. Car B starts at the starting line but has a better engine than Car A, and thus Car B travels at a constant speed Vb, which is greater than Va. How far from Car B's starting line will the cars be when Car B passes Car A? 2. Relevant equations I have figured that the time to catch up = Da/(Vb-Va) 3. The attempt at a solution Using the above, I now have this: D=t(to catch up)*(Vb-Va)+Da Does this look right? thanks!
