Question

Flo measures the amount of water her high pressure sprayer uses and finds that it uses 20 gallons of water in 4 minutes and 30 gallons in 6 minutes. Complete the table, Then describe whether it makes sense to use a constant rate to describe the relationship . Explain I need help I’m confused

Answer 1

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

`(20)/(4)=5\frac{\text{gal}}{\min }`

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

`(30)/(6)=5\frac{\text{gal}}{\min }`

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.
