Seokgi went hiking with his father. It is 4 kilometers (km) and 436 meters (m) from the entrance of the mountain to the temple, and 1999 meters (m) from the temple to the top of the mountain. If Seokgi went up starting from the entrance of the mountain through the temple and to the top of the mountain, and then came down the same road, how many kilometers (km) did he walk?
