The number of kg of water (W) in s human body varies directly as the total body weight (B). A person who weighs 50 kg contains 36kg of water. How many kilograms of water are in a person weighing 60 kg?
----
W = k*B
---
Solve for "k" using "A person who weighs 50 kg contains 36kg of water."
36 = k*50
k = 36/50
----
Equation:
W = (36/50)B
-----
Solve "How many kilograms of water are in a person weighing 60 kg?"
W = (36/50)60
W = 43.2kg
