Answer:
500 cm
Explanation:
Diameter of Milky Way = [tex]1\times 10^5\ ly[/tex]
Here, this distance is equal = 25 cm
[tex]1\times 10^5\ ly=25\ cm[/tex]
[tex]\\\Rightarrow 1\ cm=\frac{1}{25}\times 10^5\ ly\\\Rightarrow 1\ cm=0.04\times 10^5\ ly\\\Rightarrow 1\ ly=\frac{1}{0.04\times 10^5}\ cm[/tex]
Distance between the Andromeda galaxy and Milky Way is 2 million ly
[tex]2\times 10^6\ ly=2\times 10^6\times \frac{1}{0.04\times 10^5}\\\Rightarrow 2\times 10^6\ ly=500\ cm[/tex]
Hence, the plates would be 500 cm apart
