That tells you it is rails 4.0.0 as activemodel is one of the
components. However, rather than seeing what versions are installed
(there could be more than one version of the gems installed) look in
the file Gemfile.lock in the applications root folder and you will see
what versions it /requires/.

I suggest you work right through a good tutorial such as (which is free to use online) which will show you
the basics of rails. A few days spend doing that will save you time
in the long run.

If you want this for development work then I suggest you install rails
using rvm [1]
That will give you a complete working setup in a few minutes.
