      No, you just do it in your head, provided you can do your arithmetic as well as a child can.

        First you need to know there are 1760 yards in a mile which isn’t common. Next you need to divide 1760 by 200. If you ask a child, they aren’t going to know to round up to 1800 and say 9 as an estimate.
