Answer:
about 10 trillion kilometers
Explanation:
c = Speed of light = [tex]3\times 10^8\ m/s[/tex]
t = Seconds in one year = [tex]365.25\times 24\times 60\times 60[/tex]
1 Light year
[tex]1\ ly=ct\\\Rightarrow 1\ ly=3\times 10^8\times 365.25\times 24\times 60\times 60=9.46728\times 10^{15}\ m\\ =9.46728\times 10^{15}\times 10^{-3}\\ =9.46728\times 10^{12}\ km\approx 10\ trillion\ km[/tex]
The answer is a. about 10 trillion kilometers
