Suppose you can measure your dog's happiness of a scale from 1,000 to 10,000, where 10,000 is the most happy. You realize its happiness is directly proportional to the length of its walk. When you go on a 10 minute walk it has a happiness of 2272 afterwards.
How long does the walk need to be to maximize its happiness?
Round to the nearest minute.
