A player on a miniature golf course must get around a barrier 3 feet from the hole. The player putts the ball from the lower left-hand cornerdirectly opposite from the hole in the lower right-hand corner. The ball bounces of the upper side of the course at the halfway mark. The course is a perfectly flat, 6-foot by 8-foot rectangle, and the barrier extends 4 feet from the side of the course that connects the starting point and the hole. Note that the angle at which the ball hits the upper wall is the same as the angle of rebound
