A man is walking home with his dog at a steady 4mph. With 6 miles to go the dog is let off the leash and runs all the way home at 6 mph. The dog immediately turns and runs back to the man at the same speed, and upon meeting him it turns and runs home again. It continues to run back and forth at the same speed until the man reaches home. What distance has the dog run since being let off the leash?
about 8.99999999999999 miles after about 1.4999999999 hours
