Question

A friction-less board has the shape of an equilateral triangle of side length 1 meter with
bouncing walls along the sides. A tiny super bouncy ball is fired from vertex A towards the
side BC. The ball bounces off the walls of the board in times before it hits a vertex for the
first time. The bounces are such that the angle of incidence equals the angle of reflection. The
distance traveled by the ball in meters is of the form N. where N is an integer. What is the
value of N?​
