A person walks 5 km north, then 3 km east, and finally 5 km south. Where is he now in relation to his starting point?

Step 1: The person starts at a point, which we can call the starting point.
Step 2: The person walks 5 km north. Now, he is 5 km north of the starting point.
Step 3: Next, the person walks 3 km east. Now, he is 5 km north and 3 km east of the starting point.
Step 4: Finally, the person walks 5 km south. This means he moves back down 5 km from his current position.
Step 5: Since he was 5 km north and walks 5 km south, he is now back at the same north-south level as the starting point.
Step 6: However, he is still 3 km east of the starting point because he did not move west or back to the starting point in the east-west direction.
