  1. A solution to this problem is available from a link at the bottom of the page you get to if you go to the link above. When I told Hendree about this problem, he solved it by using WolframAlpha. The specific problem at the time was this:

    “The distance from New York to London is 3459 miles. A plane which travels at 500 mph when there is no wind leaves New York and flies toward London when there is a 15 mph tailwind. The pilot turns around at point P and heads back to New York. The trip from point P to New York took the same time as the trip from point P to London would have taken had he kept going. What’s the distance to the nearest mile from New York to point P?”

    Using distance/rate=time it can be seen that

    x/485=(3459-x)/515
