A boy, a girl and a dog are standing together on a long, straight road. Simultaneously, they all start walking in the same direction: The boy at 4 mph, the girl at 3 mph, and the dog trots back and forth between them at 10 mph. Assume all reversals of direction instantaneous.

In one hour, where is the dog and in which direction is he facing?

Impossible to tell really, because when the dog collapses from exhaustion and dies, gravity will take over and drop it anywhere. That is, of course unles it's Lassie, and it has a few stand ins to take over..he he.
