Current Attempt in Progress

Water flows out of a $\backslash (60\backslash$mathrm$\{$ft$\}^\{3\}\backslash )$ tank through a $3-$in$-$diameter pipe at a speed of $\backslash (4\backslash$mathrm$\{$ft$\}/\backslash$mathrm$\{$s$\}\backslash )$ as water flows into the tank at another location at a rate of $430$ gpm $.$ If the tank is initially half$-$full, how long will it be before the tank is completely full of water?
