ANSWER THE QUESTION A, B, C OR D! NOT HARD!

You should swallow the 80.8 but then shout for the alien in the back ground to eat it! It’s that simple man, that simple!.

Yes, you are correct. The correct conversion factor to change meters to kilometers is A. 1000 m/1 km. To understand why, we need to know that there are 1000 meters in 1 kilometer. Therefore, when converting from meters to kilometers, we divide the number of meters by 1000. This is done by setting up the conversion factor with meters in the numerator and kilometers in the denominator, so that the units cancel out correctly. So, by multiplying 18 meters by 1000 m/1 km, we can convert it to kilometers and get the answer.

no, you already have meters. You want km.

So, you want to divide by m, so they cancel

1m * 1km/1000m = 1/1000 km

If you multiply by A, you end up with

1m * 1000m/km = 1000m^2/km
which makes no sense
