Operations: Metric Length Practice 8

Question

Accepted Answer

For this problem, we need to add 2 kilometers with 450 m. Now, in order to add these units together, we first need them to be the same unit. So I need to convert either kilometers to meters or meters to kilometers. Doesn't really matter which one I choose, it's just my preference. Here, I'm going to convert kilometers to meters. So first, let's recall our acronym for the prefix lie. King Henry doesn't usually drink chocolate milk, where here our unit base is meters. So in order to go from kilometers K to our base unit of meters, we're going to move our decimal place 3 places to the right. So doing that, we get 2000 m plus 450 m, which gives us a total of 2450 m.
