Quandaries and Queries A salesman traveled due west from city A to city B. The distance he traveled, that is the ditance from A to B, was X miles. He returned from B to A and found that he had traveled half the distance, X/2 miles. How can that be? Thank you, Liz Hi Liz, I have two replies, one from Penny and another from Chris. Penny: The problem doesn't say what direction he travelled on his return trip but I do know that he was wearing a fur coat and hat, winter boots and snowshoes. Chris: Of course, this is not a mathematics question. There could be many acceptable answers. Possible answer 1. It sounds a bit like the riddle whose answer is that the story takes place at the North Pole: At a point where the latitude is a circle of length 1.5X miles, you can travel X miles west to your destination, then continue .5X miles west to return. Possible answer 2. There is a one-way street X miles long from A to B. In the other direction the road is half as long. (This is actually the case when traveling from my office to my locker in the Phys Ed building, except the appropriate units are meters and not miles: There is a door blocking the short route going toward my locker, so I must go the long way around. For the return trip, I can exit from that door and walk a much shorter distance.) Chris Go to Math Central
