Answer:
1 AU
Explanation:
Distance between Sun and Earth is given as
[tex]r = 1.5 \times 10^{11} m[/tex]
Now this new value of distance is taken as reference and defined in terms of new units
This new unit is known as AU = Astronomical Unit
So distance between Sun and Earth is equal to 1 AU which means it is
[tex]1 AU = 1.5 \times 10^{11} m[/tex]
