Watch My Horse, PleaseMath brain teasers require computations to solve.
Two posts, 1 foot to a side, are seated in the ground exactly 2 feet apart. My horse is tied to an anchor on the outside of one post with a rope that is 30 feet long. He likes to walk, but can only go in circles due to the rope and posts. How many times can he go around the posts before he runs out of rope?
One trip around the posts consists of 3 feet on each post, as he does not waste rope on the sides facing each other, plus 4 feet for the two gaps between the posts, making one trip around the posts 10 feet in total. 30 divided by 10 equals 3 laps around the posts.
