Put it all into the same measurement unit -
Kim: 48,600 seconds. (13.5*60=810, 810*60=48600)
Javis: 50,700 seconds. (845*60=50,700)
Monica: 49,500 seconds.

800 hm = _____ cm 8 0.08 8,000,000 80,000

il63 [147K]

To solve this conversion factor problem we are going to multiply our original quantity 800hm by conversion factors (expressed as fractions) in order to cancel units until we get centimeters:
We know that 1 hectometer= 100 meters, so our first conversion factor expressed as a fraction is $\frac{100m}{1hm}$
We also now that 1 meter = 100 centimeters, so our second one is $\frac{100cm}{1m}$

Now that we have our fractions, lets multiply our original quantity by them to get our answer in the required units:
$800hm( \frac{100m}{1hm} )( \frac{100cm}{1m})=8000000cm$

We can conclude that 800hm are 8,000,000cm
