Problem Statement
We have a pool table meters long and meters wide with a single ball in the center. We throw the ball in a straight line and, after traveling meters, it stops at a corner of the table. How many times did the ball hit the edges of the table? Note: When the ball rebounds on the edge of the table, the two angles that form its trajectory with the edge of the table are the same.
