so the hose can do 4.74 gallons in 1 minute, how many minutes will it take for 294 gallons?
[tex]\bf \begin{array}{ccll}
gallons&minutes\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
4.74&1\\
294&m
\end{array}\implies \cfrac{4.74}{294}=\cfrac{1}{m}\implies m=\cfrac{294\cdot 1}{4.74}
\\\\\\
m\approx 62.0253164556962[/tex]
and since there are 60 minutes in 1 hour, how many hours is that?
[tex]\bf \begin{array}{ccll}
hours&minutes\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
1&60\\
h&62.0253164556962
\end{array}\implies \cfrac{1}{h}=\cfrac{60}{62.0253164556962}
\\\\\\
\cfrac{1\cdot 62.0253164556962}{60}\approx h[/tex]
