It looks like you started traveling without enough time remaining in your time pool to reach Nocaneb in a single turn. When the next turn happens (in about two hours), you should arrive, and it will stop saying you are traveling.
Any time you are traveling, if you look at your Travel page, it should tell you how much time it will take you to arrive at your destination. That amount will be deducted from your time pool at the next turn change if you have enough time left, and if you don't have enough, you'll continue traveling until you do (gaining 8 hours every turn).
If there are any mentors in your realm, I recommend you connect up with one of them, who will be able to teach you the ropes more easily.
