Okay, can someone please tell me how you find how far light has traveled since the big bang. I know the answer is 13.2 billion year, and I know you can get it by using(adsbygoogle = window.adsbygoogle || []).push({});

c / H = answer in parsecs

Then I convert parsecs to light years and I can get the time and distance from there. But, how do you get the speed of light divided by Hubbles constant. It doesn't make sense to me.
