Answer:
You could use kilometers when you're describing how far away your neighbor is. If they lived down the street you could say they lived 2 kilometers away. Or when you're measuring a height as well.
Step-by-step explanation:
Kilometer is 1093.61 yards so yard is 3 feet. So a reasonable answer would be your neighbor, or someone who lived a little bit away from you. You could also use it to describe height. This is a weird example but usually when they measure tsunamis they use kilometers to measure the height.
