The number of kg of water (W) in a human body varies directly as the total body weight (B). A person who weighs 75kg cotains 54kg of water. How many kilograms of water are in a person weighing 95kg?
-------------
General Equation:
W = kB
-----
Find "k" if W=54 and B = 75
54 = k*75
k = 0.72
-----
How many kilograms of water are in a person weighing 95kg?
W = 0.72*95
W = 68.4 kg of water
