Walking 12 km usually takes about 2 hours to 3 hours. At a normal comfortable pace of 5 km/h, expect roughly 2 hours 24 minutes. Your real time can change with pace, hills, heat, stops and current fitness.
A 12 km walk is a real endurance walk. It is not extreme, but it deserves planning: footwear, water, route choice and pacing matter more than they do for a short neighborhood walk.
