Question

Suppose that there are 150,000,000 people in Yourtown. And, suppose that Yourtown uses 310 × 109cubic meters of water per year. What is the amount of water (in cubic meters) used per person each year in Yourtown?

Answer 1

Given:

The number of people = 150,000,000.

The amount of water used in town = 310 × 109 cubic meters.

Required:

We need to find the amount of water (in cubic meters) used per person each year.

Step-by-step explanation:

`The\text{ amount of water used per person =}\frac{The\text{ amount of water used}}{The\text{ number of people}}`

Substitute the number of people = 150,000,000 and the amount of water used in town = 310 × 109 cubic meters in the equation.

`The\text{ amount of water used per person =}(310*109)/(150000000)`

`The\text{ amount of water used per person =}(33790)/(150000000)`

`The\text{ amount of water used per person =}(3379)/(15000000)`
`The\text{ amount of water used per person =}0.000225267\text{ cubic meters}`

Final answer:

`The\text{ amount of water used per person =}0.000225267\text{ cubic meters}`
