Question

An air conditioning system can circulate 390 cubic feet of air per minute. How many cubic yards of air can it circulate per minute? The air conditioning system can circulate about cubic yards of air per minute . (Type an integer or a decimal rounded to one decimal place as needed.)

Answer 1

To solve the exercise you can use the rule of three, like this

`\begin{gathered} 1\text{ cubic yard}\rightarrow27\text{ cubic feet} \\ x\text{ cubic yards}\rightarrow390\text{ cubic feet} \end{gathered}`
`\begin{gathered} x=\frac{390\text{ cubic feet}\ast1\text{ cubic yard}}{27\text{ cubic feet}} \\ x=14.4\text{ cubic yards} \end{gathered}`

Therefore, the air conditioning system can circulate about 14.4 cubic yards of air per minute.
