Answer: [tex]9\times10^7\ miles[/tex]
Step-by-step explanation:
Given: The estimated distance from Earth to the moon[tex]=2.25\times10^5\ miles[/tex]
If the distance from Earth to the sun is approximately 400 times farther.
Then, the distance from Earth to the sun[tex]=400\times2.25\times10^5[/tex]
[tex]=900\times10^5\ miles\\=9\times10^7\ miles[/tex]
Therefore, the approximate distance from Earth to the sun=[tex]9\times10^7\ miles[/tex]
