Answer:
Time required to completely fill this container = 78.43 seconds
Step-by-step explanation:
Volume of container = 4 m³
Rate of filling of container = 0.051 m³/s
We have the equation
![\texttt{Time required}=\frac{\texttt{Volume of container}}{\texttt{Rate of filling of container}}](https://img.qammunity.org/2020/formulas/physics/college/kan3pc2o9alid6ko9xj8ep8dv4ckfi9wqk.png)
Substituting
![\texttt{Time required}=(4)/(0.051)=(4000)/(51)=78.43 s](https://img.qammunity.org/2020/formulas/physics/college/z3cgtjak9qfxorcy486z4lmdjyhvr0fc0v.png)
Time required to completely fill this container = 78.43 seconds
