Question

The approximate average distances from the sun to Saturn and Jupiter are listed below:
Saturn: 1, point, 4, 3, times, 10, to the power 91.43×10
9
kilometers
Jupiter: 7, point, 7, 8, times, 10, to the power 87.78×10
8
kilometers
How many times farther from the sun is Saturn than Jupiter? Write your answer in standard notation, rounding to the nearest tenth.

Answer 1

Compute the ratio:

(1.43 × 10^9) ÷ (7.78 × 10^8) = (1.43/7.78) × 10^(9−8) = (1.43/7.78) × 10 ≈ 0.18385 × 10 ≈ 1.8385.

Rounded to the nearest tenth: 1.8.

So Saturn is about 1.8 times farther from the Sun than Jupiter.
