Math Fun: Conversion
Question:
Saturn is 9.5 AU from the sun. What is that distance in km?
We start by first knowing how many km are in an AU:
1.49 x 10
8
km = 1 AU
We then multiply by a fraction of the above conversion:
The units we want to convert
into
are in the numerator (the top part of the fraction).
The units we want to convert
out of
are in the denominator (the bottom part of the fraction).
9.5 AU X
1.49 x 10
8
km
1 AU
= 14.2 x 10
8
km = 1.42 x 10
9
km
Answer:
Saturn is 1.42 x 10
9
km from the sun.
