The planet Neptune is approximately 4.5 * 10^9 kilometers from the sun. The planet Venus is approximately 1.1 * 10^8 kilometers from the sun. Which is the best estimate of how many times as far from the sun Neptune is as Venus?
A. about 4 times as far
B. about 40 times as far
C. about 400 times as far
D. about 4,000 times as far

4.5/1.1 * 10^1
looks like about 40
What is correct answer
To find the best estimate of how many times as far from the sun Neptune is as Venus, we need to divide the distance from the sun to Neptune by the distance from the sun to Venus.
Distance from the Sun to Neptune = 4.5 * 10^9 kilometers
Distance from the Sun to Venus = 1.1 * 10^8 kilometers
Dividing the distance to Neptune by the distance to Venus:
(4.5 * 10^9 km) / (1.1 * 10^8 km)
To simplify this division, we can adjust the decimal places by dividing the numerator and denominator by 10^8:
(4.5 * 10^(9-8)) / (1.1 * 10^(8-8))
Simplifying further:
4.5 / 1.1
Now, let's calculate this division:
4.5 / 1.1 ≈ 4.09
So, the best estimate of how many times as far from the sun Neptune is as Venus is around 4 times.
Therefore, the correct option is A. about 4 times as far.
