Run Tommy Run!
RAY: This has to do with my brother.
Tommy decided one day after looking in the mirror, that he needed some exercise, and he needed it now! And since his bike had two flat tires, he decided to go for a jog.
So the next morning at the crack of noon, he laces up his Keds, and begins jogging right outside his front door. First he runs on a level road, then he comes to a hill and runs to the top. When he gets to the top of the hill, he turns around and he runs back exactly the way he came.
Now, on level ground, Tommy can run at 8 miles an hour. Uphill, 6 miles an hour. And downhill, 12 miles an hour. Upon his return home, and before collapsing on the kitchen floor, he notices that he had run for exactly two hours.
So the question is, how far did he run? And it appears that there is not enough information here to solve the problem, but there is.
Think you know? Drop Ray a note!
