$\LARGE{\bf{\underline{\underline\color{purple}{Solution:-}}}}$

$\boxed{ \sf \blue{We \: have \: to \: find \: the \: time \: taken \: to \: pump \: 857692\: litres \: of \: water }}$

$\boxed{ \sf \orange{ Formula }}$

$\begin{gathered}\begin{gathered}: \implies \underline{ \boxed{\displaystyle \sf \bold{\: \frac{Water\: to \: be \: pumped}{Water \: pumped \: in \: one \: hour } }} }\\ \\\end{gathered}\end{gathered}$

$\begin{gathered}\begin{gathered}: \implies \displaystyle \sf \: \frac{857692}{386} \\ \\ \\\end{gathered}\end{gathered}$

$\begin{gathered}\begin{gathered}: \implies \underline{ \boxed{\displaystyle \sf \bold{\: Time \: = \: 2222 hours }} }\\ \\\end{gathered}\end{gathered}$
