You drained the water from your pool at the end of the summer. It took 60 minutes to drain 1,800 gallons of water. On average, by what amount did the water in the pool change per minute?

-30 gallons per minute

it actually is -30

I showed you how to do the last problem. Now it's your turn.

I'll be glad to check your answer.

1800/60=30 but i get confused when it has to be positive or negative

-300 gallons per minute

-30 gallons per minute

30 gallons per minute

300 gallons per minute

those are the answer choices and the answer i got was 30 but i need to know if it is -30 or 30

no

To find the average change in the amount of water in the pool per minute, we need to determine the total change in the amount of water in the pool divided by the total time it took to drain the water.

In this case, the total change in the amount of water in the pool is 1,800 gallons, and the total time it took to drain the water is 60 minutes.

So, to find the average change per minute, we divide the total change by the total time:

Average change per minute = Total change / Total time

= 1,800 gallons / 60 minutes

= 30 gallons per minute

Therefore, on average, the water in the pool changed by 30 gallons per minute.
