Answer:
6 units
(Use the distance formula and plug in everything)
The amount of water that is turned in a minute is 5.2d. Given the fact that initially was 350 gallons of water everything you pour needs to be added to the initial amount. So the answer is V(x) = 350+5.2x (D). I hope that this is the answer that you were looking for and it has helped you.
If my math is right it should be B)
First, you find out how much can be filled in 1 minute. Then you divide that into 120 to get your answer.
To find out how much can be filled in 1 minute, take the time and divide it into the volume. We'll use the second row (2 minutes and 8 gallons.)
8/2=4. So it takes 1 minute to fill 4 gallons. Now, you just divide 4 into 120.
120/4=30
It takes 30 minutes to fill the pool up to 120 gallons.
