At first she runs on completely flat ground, and then to the<br /> top of a hill. Then she turns around and runs back exactly the same way she came: down the<br /> hill and back to her apartment. When she gets home she realizes she has ran for exactly 1<br /> hour.<br /> <br /> Sally knows she can run at 8 miles an hour on flat terrain, at 6 miles an hour going up hill,<br /> and 12 miles an hour running down hill. How many miles did Sally run?<br /> <br /> [[Category:Velocity puzzles]]</div>
