The Attempt at a Solution
I'm having some trouble figuring out how to do this problem. The homework is submitted online so I can't tell if I'm doing the problem completley wrong or if my answer is off by a little bit. Can anyone help me figure this out? Don't you just have to convert mph to light years and then multiply that by how much time is in a century?
