Answer 1

The ratio between the two distances is

`(4\cdot 10^7)/(4\cdot 10^5) = (10^7)/(10^5)`

The rule to divide power is to subtract the exponents:

`(a^b)/(a^c) = a^(b-c)`

So, you have

`(10^7)/(10^5) = 10^(7-5) = 10^2 = 100`

So, it's about 100 times farther

Answer 2

Explanation:

The moon, of course, orbits around and around the earth and together the two of them orbit the sun. Our planet and its satellite are separated by an average distance of about 240,000 miles. The distance varies somewhat but the two are never more than 253,000 miles apart. Hence the distance between them and Venus remains roughly the same. In the sky, the moon and Venus may look close enough to collide ¬but Venus is always at least 25 3/4 million miles farther away and sometimes more than 160 million miles.
