Answer :
A 69 kg person would have approximately 46 kilograms of water in their body.
The number of kilograms of water in a human body varies directly as the mass of the body. In other words, the more mass a person has, the more kilograms of water they will have in their body.
To solve this problem, we can use the concept of direct variation. We are given that a 93-kg person contains 62 kg of water. We can set up a proportion to find the number of kilograms of water in a 69 kg person.
Let x represent the number of kilograms of water in the 69 kg person.
Using the direct variation equation, we can write:
93 kg / 62 kg = 69 kg / x
To solve for x, we can cross-multiply:
93 kg * x = 62 kg * 69 kg
Now, we can solve for x by dividing both sides of the equation by 93 kg:
x = (62 kg * 69 kg) / 93 kg
Calculating this expression, we find that x is approximately 46 kg.
In summary, the number of kilograms of water in a human body varies directly with the mass of the body. Using the given information, we can set up a proportion to find the number of kilograms of water in a 69 kg person. By solving the proportion, we find that a 69 kg person would have approximately 46 kilograms of water in their body.
