It doesn't sound like brakes to me, but just to eliminate that possibility I would just jack up the wheels and then spin them to see if the calipers are sticking. The next thing I would do if you feel comfortable, is bring it up to 20 mpg where the noise starts and shut off the engine and coast does the noise go away? That would tell you if it is something in or on the engine like a worn bearing in a pully. Without the engine noise it will be easier to isolate the noise you are hearing. Also, if you put it in park and rev the engine does the sound change pitch or go away?
