Feel like a physics problem, anyone?

I haven't done physics in over 4yrs, but it seems pretty straightforward, just set up your equations to equal eachother and solve for her mass, you'll find stuff will cancel out. I'm sorry man, I don't believe in giving answers, but after you figure out the right equation it becomes easy.

good luck
 
Easiest way to do it is to look at the changes in center of mass. Since Ricardo is the heavier of the two, we will treat his movement as positive and Carmelita's movement as negative.

mRicardo*dRicardo-mCarmelita*dCarmelita = (mRicardo+mCarmelita+mCanoe)*dTotal

70*3.1-x*3.1 = (70+x+27)*.374
217-3.1x = 36.278+.374x
-3.474x = -180.726
x = 52.02 kg = mass of Carmelita

I see...thx, I didn't realize that the displacement of the canoe was the change in center of mass.
