Lateral Thinking

One horse traveled for a whole day and at the end it turned out that two of its legs covered 30 miles, whereas the other two covered 31 miles. How is this possible?

Solution

The horse was operating a mill and was traveling in a circle. Thus its outer legs covered larger distance than its inner legs.
