Answer 1

Which of the following is the most appropriate unit to describe the rate at which water flows out through a standard household faucet?

Minutes per gallon, because the independent quantity is volume of water in gallons and dependent quantity is time in minutes.

Gallons per minute, because the independent quantity is volume of water in gallons and dependent quantity is time in minutes.

Minutes per gallon, because the independent quantity is time in minutes and dependent quantity is volume of water in gallons.

Gallons per minute, because the independent quantity is time in minutes and dependent quantity is volume of water in gallons.

Answer 2

Remember the definitions of independent and dependent quantities. This is very important if you seek to continue knowledge of science and mathematics. Independent quantitative variables represent variables that you yourself manipulate/change. Dependent quantitative variables represent variables that change BECAUSE of the independent variable.

In this case, when you manipulate a water faucet, what are you changing? Certainly not the time, since time is constant. Instead, you're manipulating the amount of water flowing out of the faucet, making the quantity of water the independent variable. In turn, this makes the dependent variable the amount of time, since the amount of time at which a certain, particular amount of water flows out of the faucet changes based upon how much water is actually flowing from the faucet. Therefore, since the independent quantity is amount of water in gallons and the dependent quantity is amount of time in minutes, the correct answer is...

(B): Gallons per minute, because the independent quantity is volume of water in gallons and dependent quantity is time in minutes.
