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

2 times

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 * 10^(8)\ miles`

Distance of Uranus from Sun,
`D_(2) = 1.787 * 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) * 2 = 8.867 * 10^(8)\ miles * 2\\\Rightarrow 17.734 * 10^(8)\ miles\\\Rightarrow 1.7734 * 10^(1) * 10^(8)\ miles\\\Rightarrow 1.7734 * 10^(8+1)\ miles\\\Rightarrow 1.7734 * 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.
