ya. I can explain it. It is a very imple theory . The more nearer you are to the window , the more is the range of up to how much length can you see what is at your backside. Her , 12 m is so long , that the panter can only see in the mirror 1m of painted wall behind its back. Thereby , 1m is the correct answer
