Given :
Number of gallons in the aquarium after 14 minutes = 5.6 gallons
Time taken = 14 minutes
Rate at which Jerry is filling the bucket :
[tex]\begin{gathered} =\text{ }\frac{Number\text{ of gallons }}{time\text{ taken}} \\ =\text{ }\frac{5.6\text{ gallons}}{14\text{ mins}} \\ =\text{ 0.4 gallons per mins} \end{gathered}[/tex]Rate = 0.4 gallons per mins
