Question

The approximate average distances from the sun to Neptune and Venus are listed below:
Neptune: 4, point, 5, times, 10, to the power 94.5×10
9
kilometers
Venus: 1, point, 0, 8, times, 10, to the power 81.08×10
8
kilometers
How many times farther from the sun is Neptune? Write your answer in standard notation, rounding to the nearest tenth.

Answer 1

Neptune ≈ 4.5×10^9 km, Venus ≈ 1.08×10^8 km.

Ratio = (4.5×10^9) / (1.08×10^8) = (4.5 / 1.08) × 10^(9−8) = 4.1666... × 10 = 41.666... ≈ 41.7

Neptune is about 41.7 times farther from the Sun than Venus.
