Which of the following is the most appropriate unit to describe the rate at which water flows out through a standard household faucet?
Question 13 options:
1) Minutes per gallon, because the independent quantity is volume of water in gallons and dependent quantity is time in minutes.
2) Gallons per minute, because the independent quantity is volume of water in gallons and dependent quantity is time in minutes.
3) Minutes per gallon, because the independent quantity is time in minutes and dependent quantity is volume of water in gallons.
4) Gallons per minute, because the

I suppose theoretically, the answer could go either way... if you knew the flow rate, a desired amount of water could could take a certain amount of time so water volume would be independent and time would be dependent..
BUT, I think the question is looking for the other answer. The amount of water that flows out is dependent on how long the faucet runs. If you run the faucet for only a second, you might only fill up part of a glass. If you run it for 2 hours, you might flood your kitchen. So the volume *depends* on time. Time is *independent*.
As such, you'd probably talk about the flow rate (rate of change of the given function of volume) as the Volume/Time
Which is the correct answer I should pick?
Which is a unit of time:
Which is a unit of volume:
If you divide volume by time using the above units do you get:

how long ago did you post this question? 19 minutes ago or 19 gallons ago?
19 minutes ago
right. so minutes are a unit of time, then by default gallons must be a unit of volume right?
so if you want the rate of flow of volume, you want how fast its flowing. When you talk about how fast a car goes, you say its going X miles per hour. Same thing here. We're talking about how fast water flows so X gallons per minute
I would say its d because The independent variable is time and dependent is quantity of water
