So if he were to hike two more km, then he would be 1/2 done. He is already 17 km done, so add 2 km with 17 km and get 19 km. This is half. So multiply 19 by 2 and get 38 km. So the total length of kilometers of Josh’s hike is 38. An equation can be represented as: 17 + 2 + 1/2x = 38 and x represents the total length of kilometers of his hike. Hope this helps. Feel free to ask more questions and ask me any questions about my explanation.
