It really depends what's expected of you outside of those 11 hours. If your assessment that semester is coursework heavy then 11 may well be quite a lot, if it's exam heavy then 11 may be basically nothing. For example in first year engineering you can pretty much treat it as a 9-5 day, once you've finished lectures/labs you can go home and forget about the world, but it's also a 9-5 day everyday. Now I'm in 4th year I have 7 contact hours per week, but everything is also very assignment based to the point where even 7 may be a bit high. You also need to take into account the time it takes to get ready and go to the lectures, if you've got a 30 minute walk to and from uni then 2 hours of lectures suddenly means a 3 hour commitment, and any pre-reading can add 1-2 hours quite easily.
For Hispanic Studies and Spanish I would guess that's probably about right as you'll be expected to do a lot of coursework, language practice, and pre-reading, it may even be slightly on the low side.
