Answer:

$(1)/(4,650)\ astronomical\ unit$

or

$2.15*10^(-4)\ astronomical\ unit$

Explanation:

we know that

One astronomical unit is about 93,000,000 miles

so

using proportion

Find out how many astronomical unit represent 20,000 miles

Let

x ----> the number of astronomical unit

$(1)/(93,000,000) =(x)/(20,000)\\\\x=(20,000)/(93,000,000)\ astronomical\ unit$

simplify

$(1)/(4,650)\ astronomical\ unit$

or

$2.15*10^(-4)\ astronomical\ unit$
