Answer:
[tex]x=0.017 AU[/tex]
Explanation:
We can use the equation of speed in terms of distance. We know that the speed of light is constant value so we will have:
[tex]v=\frac{x}{t}[/tex]
[tex]x=v*t[/tex]
[tex]x=3*10^{8}*8.417[/tex]
[tex]x=2.53*10^{9}m[/tex]
Now we know that [tex]1 AU = 1.496*10^{11}m[/tex]
[tex]x=0.017 AU[/tex]
I hope it helps you!
