Respuesta :

Given, 20 gallons per 4 minutes, let's find the unit rate:

[tex]\frac{20}{4}=5\frac{\text{gal}}{\min }[/tex]

Also, given 30 gallons per 6 minutes, that also has an unit rate of:

[tex]\frac{30}{6}=5\frac{\text{gal}}{\min }[/tex]

Thus, the constant of proportionality is 5.

Let's complete the table:

Yes, it does make sense. Because a high pressure sprayer should ideally be using a constant rate of water.
