Question

The average distance from Pluto to the sun is about 6 x 10^9 kilometers. The average distance from mars to the sun is 2 x 10^8 kilometers. The average distance from Pluto to the sun is about how many times as great as the average distance from Mars to the sun?

Answer 1

`(6 * 10^9 \ km)/(2 * 10^8 \ km)=(6)/(2) * (10^9)/(10^8)=3 * 10^(9-8)=3 * 10^1=30`

The average distance from Pluto to the Sun is 30 times as great as the average distance from Mars to the Sun.
