Question

A newly discovered solar system is found 300 billion kilometers from the sun. How many AU does this represent? Show your work.

Answer 1

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
