Question

Saturn is 8.867 × 10^8 miles away from the Sun. Uranus is 1.787 × 10^9 miles away from the Sun. Approximately how many times farther is Uranus from the Sun than Saturn is?

Answer 1

Answer:

2 times

Step-by-step explanation:

Please refer to the image attached of our solar system in which Saturn and Uranus are clearly visible.

Distance of Saturn from Sun, $D_{1} = 8.867 \times 10^{8}\ miles$

Distance of Uranus from Sun, $D_{2} = 1.787 \times 10^{9}\ miles$

We have to find, how many times the Uranus is far from Sun than Saturn is far from Sun.

Let us begin by multiplying the distance of Saturn from Sun by 2: $D_{1} \times 2 = 8.867 \times 10^{8}\ miles \times 2\\\Rightarrow 17.734 \times 10^{8}\ miles\\\Rightarrow 1.7734 \times 10^{1} \times 10^{8}\ miles\\\Rightarrow 1.7734 \times 10^{8+1}\ miles\\\Rightarrow 1.7734 \times 10^{9} \approx D_{2}$

From above, we can say that $D_{2}$ is approximately twice of $D_{1}$.

In other words, we can say that Uranus is at approximately twice distance from Sun than that of Saturn is.
