Q
Q: A person walks 5 km North, then 5 km East, and finally 5 km South. How far is he from his starting point? (2023)
Solution:
After walking North and then South, he returns to the same latitude, and since he walked East, he is 5 km East of the starting point.
Steps: 6
Show Steps
Step 1: The person starts at a point, which we will 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 5 km East. Now, he is 5 km North and 5 km East of the starting point.
Step 4: Finally, the person walks 5 km South. This means he moves back down 5 km to the same latitude as the starting point.
Step 5: After walking South, he is now at the same North-South position as the starting point but still 5 km East.
Step 6: Therefore, the final distance from the starting point is 5 km East.
