A person walks 10 km east, then 10 km south, and finally 10 km west. How far is he from his starting point?

Step 1: The person starts at a point, which we can call the starting point.
Step 2: The person walks 10 km east. Now he is 10 km away from the starting point to the east.
Step 3: The person then walks 10 km south. Now he is 10 km south of the point he reached after walking east.
Step 4: The person then walks 10 km west. This means he walks back towards the starting point.
Step 5: After walking 10 km west, he reaches the same point he started from.
Step 6: Since he is back at the starting point, the distance from the starting point is 0 km.
