1 AU means 1 astronomical unit or the aproximate distance from the earth to the sun 
1AU=<span>149597870.7 kiometers
1 billion=1,000,000,000
600 billion=600,000,000,000
</span>
<span>x times 1AU=600,000,000,000
x times </span>149597870.7=<span>600,000,000,000
solve for x
divide both sides by </span><span>149597870.7
</span>x=4010.75
so aprox 4011 AU's

Explanation:
Electromagnetic waves travel slowest in dense matter such as solids. On the other hand, mechanical waves travel quickly through solids. For example, sound travels fastest through solids. This difference is because EM waves do not rely on the movement of particles to travel. Since they require no medium they can travel the fastest in space or other vacuums.
