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 long after Car B started the race will Car B catch up with Car A? Express the time in terms of given quantities. T catch = ? How far from Car B's starting line will the cars be when Car B passes Car A? Express your answer in terms of known quantities.
