Adam went on a long trip. For 1/6 of the distance he walked besides the river. He then walked over a bridge for 1/12 of the distance and around a lake for 1/7 of the distance and entered a valley. He walked a further 5 Kilometres across the valley. He then hired a bike and cycled for 1/2 of the total distance of the trip. He got off bike and walked for a further 4 kilometres to his destination.
What was the total distance he covered?
