Question: On an idealised rectangular billiard table with side lengths $3 \mathrm{~m}$ and $2 \mathrm{m}$ a ball (point-shaped) is pushed away from point $M$ on the long side $A B$. It is reflected exactly once on each of the other sides as shown. at which distance from the vertex $A$ will the ball hit this side again if $B M=1.2 \mathrm{~m}$ and $B N=$ $0.8 m$?
<image1>
Choices:
(A) $2 \mathrm{~m}$
(B) $1.5 \mathrm{~m}$
(C) $1.2 \mathrm{~m}$
(D) $2.8 \mathrm{~m}$
(E) $1.8 \mathrm{~m}$ You FIRST think about the reasoning process as an internal monologue and then provide the final answer. The reasoning process MUST BE enclosed within <think> </think> tags. Please answer the final answer within the <answer> </answer> tags.
