Watch My Horse, Please
Math 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?
Answer
3 times.
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.

 Based on the size of the poles, their distance apart from each other, and the length of the rope, if the horse walks in a circle around them, how far can he get before he runs out of rope?

 The 1 foot to a side means the poles are 1 foot square, meaning the side of each pole is 1 foot long. Real thick poles...

 If it weren't for the fact that this is posted in the category "Math," I would say: as many times as he wants, as long as he changes direction regularly =) But yeah, it's in "Math," so, 3 times.

 That is actually quite humorous about him changing directions. Glad you guys liked it.
