suppose an auto racer won a 300 mile race with a time of 1:41:48.2942. At one point the racer was 70 miles closer to the finish than the start. how far had the racer gone at that point?
How far from the start was the racer?_miles

  • math -

    x+(x-70) = 300
    2x = 370
    x = 185

    So, he was 185 miles from the start, and 115 miles from the finish.

    The whole race took 3600+41*60+48.2942 = 6108.2942 seconds, so

    it took 185/300 * 6108.2942 seconds to get that far. Just convert that to hh:mm:ss in the normal way.
