The conversion factor needed to change from kilometers to meters is
D) 1000
Explanation:
The meter (m) is the SI units to measure distance.
The kilometer (km) is a sub-unit, where the prefix 'kilo' stands for [tex]10^3[/tex], or 1000. This means that:
[tex]1 km = 1000 m[/tex]
Therefore, if we have a length expressed in kilometers, we just need to multiply by 1000 to get the corresponding length in meters.
For instance, if we have a length of
L = 3.47 km
To convert in meters, we do:
[tex]L = 3.47 km \cdot (1000 \frac{m}{km})=3470 m[/tex]
