The distance of planet Jupiter from the Sun is approximately 7.8 ⋅ 108 kilometers, and the distance of planet Saturn from the Sun is 1.5 ⋅ 109 kilometers.

Question

About how many more kilometers is the distance of Saturn from the Sun than the distance of Jupiter from the Sun?

Group of answer choices

6.3 ⋅ 101 kilometers

6.3 ⋅ 108 kilometers

7.2 ⋅ 108 kilometers

7.2 ⋅ 109 kilometers

Answer 1

To find out how many more kilometers the distance of Saturn from the Sun is compared to the distance of Jupiter from the Sun, we can subtract the distance of Jupiter from the distance of Saturn.

The distances are:

• Jupiter: \(7.8 \times 10^8\) kilometers
• Saturn: \(1.5 \times 10^9\) kilometers

Let's perform the subtraction:

\[ \text{Distance of Saturn} - \text{Distance of Jupiter} = (1.5 \times 10^9) - (7.8 \times 10^8) \]

Now, we can convert \(1.5 \times 10^9\) into the same exponent as \(7.8 \times 10^8\):

\[ 1.5 \times 10^9 = 1.5 \times 10^9 = 15.0 \times 10^8 \]

Now subtract:

\[ 15.0 \times 10^8 - 7.8 \times 10^8 = (15.0 - 7.8) \times 10^8 = 7.2 \times 10^8 \]

Thus, the distance of Saturn from the Sun is approximately \(7.2 \times 10^8\) kilometers more than that of Jupiter.

The correct choice is:

7.2 ⋅ 10^8 kilometers.
