EMT-B in Kentucky takes 6 semester hours (one class meeting 8 hours/wk). We have no EMT-Intermediate in KY and Paramedic is a 2 year course with a lot of ambulance/hospital time. I'm sure this is about the same in every state.
EMT-B isn't a difficult course if you will apply yourself and it's very valuable info even if you never work for a ambulance service or FD...Good Luck!
