With a hand-me-down phone, it would be best to just do a factory reset so you can start from scratch. Should be somewhere under Settings > Privacy > Factory Data Reset

If you don't want to do that though, I don't remember exactly how to delete a Google account on your version of Android, but it should be under Settings > Accounts somewhere.
