Answer

Explanation:

Step1: Set up the division

To find out how many times farther Uranus is from the Sun than Saturn, we divide the distance of Uranus from the Sun by the distance of Saturn from the Sun. So we have the expression $\frac{1.787\times 10^{9}}{8.867\times 10^{8}}$.

Step2: Use the rule of exponents $\frac{a\times10^{m}}{b\times10^{n}}=\frac{a}{b}\times10^{m - n}$

$\frac{1.787}{8.867}\times10^{9 - 8}$. Calculate $\frac{1.787}{8.867}\approx0.2$, and $10^{9 - 8}=10^{1} = 10$. Then $0.2\times10 = 2$.

Answer:

B. 2 times
