The value of Y in AU for the distance between the sun and the two galaxies is 1,333.3 AU.
The given parameters;
The distance between the sun and the two galaxies is calculated as follows;
Y = 600 billion km - 400 billion km
Y = 200 billion km
150 million km = 1 AU
200 billion km = ?
[tex]\frac{1 \ AU}{150 \times 10^6 \ km} \times 200 \times 10^9 \ km= 1,333.3 \ AU[/tex]
Thus, the value of Y in AU for the distance between the sun and the two galaxies is 1,333.3 AU.
