Frictional unemployment is present even when labor markets are working well.
eliminate
b) is the result of worker skills not matching the jobs available.
c) is zero when the economy achieved the natural rate of unemployment.
d) exists only when the economy is in the natural rate of unemployment

I’m pretty sure the answers are:

250 meters=0.25 kilometers

12 meters=0.012 kilometers

1 meter=0.001

5 kilometers=5,000 meters

20 kilometers=20,000 meters

0.3 kilometers=300 meters

For future reference, you can find the constant of proportionality by dividing the x value by the y value. Then you multiply each given number by the constant of proportionality, and that’ll give you your answers.

Unfortunately, I don’t know the answers to the last few questions. Sorry about that!
