Question: If a person walks 5 km north, then 5 km east, and finally 5 km south, how far are they from the starting point?

Options:

Correct Answer: 0 km

Solution:

The person returns to the starting point after walking in a triangular path, so the distance from the starting point is 0 km.

If a person walks 5 km north, then 5 km east, and finally 5 km south, how far are they from the starting point?

If a person walks 5 km north, then 5 km east, and finally 5 km south, how far are they from the 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 they are 5 km north of the starting point.
Step 3: Next, the person walks 5 km east. They are now 5 km north and 5 km east of the starting point.
Step 4: Finally, the person walks 5 km south. This means they move back down 5 km from their current position.
Step 5: Since they were 5 km north before walking south, walking 5 km south brings them back to the same level as the starting point.
Step 6: Now, they are 5 km east of the starting point, but at the same north-south level.
Step 7: The final position is 5 km east of the starting point, so they are not at the starting point anymore.
