Answer:

[tex]d=v*t=(30\frac{km}{s})(3.16x10^{7})=9.48x10^{8}km[/tex]

Explanation:

Our knowable variables are velocity and time

[tex]v=30 \frac{km}{s}[/tex]

[tex]t=3.16x10^{7}s[/tex]

We know that [tex]v=\frac{d}{t}[/tex]

So, with the data that we have we can calculate distance

[tex]d=v*t=(30\frac{km}{s})(3.16x10^{7})=9.48x10^{8}km[/tex]
