Answer:
[tex]88kg\text{ of water}[/tex]
Explanation:
Here, we want to get the number of kg of water in a 132 kg person
From the question, there is a direct variation between kg of water in the human body and the mass of the body
Let the mass be m and the amount of water be w
By direct variation, with k as the proportionality constant, we have it that:
[tex]w\text{ = }km[/tex]
From the question, a 72 kg mass boy has 48 kg of water
Mathematically, we have it that:
[tex]\begin{gathered} 48\text{ = k }\times72 \\ k\text{ = }\frac{48}{72} \\ \end{gathered}[/tex]
Now, we want to get the kg of water in a 132 kg person
What we have to do here is to have k as 48/72 and solve for w
Mathematically, we have that as:
[tex]\begin{gathered} w\text{ = }\frac{48}{72}\times132 \\ \\ w\text{ = 88 }kg \end{gathered}[/tex]
