The planet Saturn from the Sun was:
[tex]9.1\times10^8[/tex]The Earth miles from the Sun is:
[tex]9.3\times10^7[/tex]The difference between them is:
[tex]\begin{gathered} (9.1\times10^8)\text{ -(9.3}\times10^7) \\ (91\times10^7)\text{ - (9.3}\times10^7) \\ \text{Factor out 10}^7,\text{ we get} \\ (91-9.3)10^7 \\ 81.7\times10^7 \\ 8.17\times10^1\times10^7 \\ 8.17\times10^{1+7} \\ 8.17\times10^8\text{ miles} \end{gathered}[/tex]Thus, the correct answer is option D
