The total distance that the hiker walked does not have any relation with the starting time nor the ending time of walking. Also it doesn`t matter is the hiker going east, west, north or south. It is related only with the distances that he walked. Therefore: d = 6 km + 4 km + 6 km + 8 km = 24 km . Answer: B ) 24 km. Hope this helps. Let me know if you need additional help!
