Walking the dog.
Jane is walking her dog, spot. She sees her friend, Dick, walking toward 
her along the same long, straight road. Both Dick and Jane are walking 
at 3 mph. When Dick and Jane are 600 feet apart, Spot runs from Dick to 
Jane, turns and runs back to Dick, and then back and forth between them 
at constant speed of 8 mph. Dick and Jane both continue walking toward 
each other at a constant 3 mph. Neglecting the time lost each time Spot 
reverses direction, how far has Spot run in the time it takes Dick and 
Jane to meet?
