Question

One astronomical unit (AU) averages about.

Answer 1

About 93 million miles or 150 km or 8 light minutes (don't know what that means) 

Answer 2

Explanation:

Astronomical unit is the one of the unit which is used to measure the average distance between the earth and the sun.

Mathematically, it can be written as :

1 AU = 149597870700 m

In other units, it is equal to :

1 AU = 92.956 million miles

or

1 AU = 15.8125 millionths of a light year

It can also be written in terms of astronomical constant as :

A³ = GM₀D² / k²

Where,

G is the gravitational constant

D is the time period of one day

M₀ is solar mass.
