Six identical

Six identical compressors inflate 180 balloons in one hour. How many balloons inflate one compressor in 10 minutes?

Correct answer:

x =  5

Step-by-step explanation:

$$\begin{gathered} t=1\text{ h}\to \text{ min}=1\cdot 60\text{ min}=60\text{ min } \\ m=180\mathrm{/}(6\cdot t)=180\mathrm{/}(6\cdot 60)={\displaystyle \frac{1}{2}}=0.5 \\ x=n=10\cdot m=10\cdot 0.5=5 \end{gathered}$$
