Question

A newly discovered solar system is found 600 billion kilometers from the sun. How many AU does this represent? Show your work.

Answer 1

Answer:

$4011$ AU

Explanation:

AU stands for astronomical unit. It is a unit of measurement in space.

One AU is equal to $1.496 * 10^8$ Kilometers.

Given -

The distance between the newly discovered solar system and the sun $= 600$ 600 billion kilometers.

$= 600* 10^9\\= 6 ^ 10^ {11}$ kilometers

Converting this distance (in kilometer) to AU , we get -

$\frac{6*10^{11}}{1.496*10^8} \\= 4.011 * 10^3\\= 4011$AU

Answer 2

1 AU means 1 astronomical unit or the aproximate distance from the earth to the sun 
1AU=149597870.7 kiometers

1 billion=1,000,000,000
600 billion=600,000,000,000


x times 1AU=600,000,000,000
x times 149597870.7=600,000,000,000
solve for x
divide both sides by 149597870.7
x=4010.75
so aprox 4011 AU's
