Worked it out in my head. I'll take the medal thanks 😂

12.5 hours, the pump displaces 1200 gallons per hour. Hence 15000 gallons divide by 1200 gallons/hour hence it’s 12.5 hours to pumped out 15000 gallons.

That’s a long way around the barn.

What if you got ducks to bring pebbles to the pool and fill it with the pebbles. Most of the water would be displaced eventually. It would be more fun to watch ducks dropping pebbles than pumping the water out and down the driveway to the city street myself.

And I would not have to pay attention for 12.5 hours.

Greetings. Based on the details given the answer is 12.5 hours. We arrived at the answer by first determining how how many gallons would be pumped in 1 hour. If 20 gallons are pumped in 1 minute, we would pumped 20 times 60 gallons in 1 hour (60 minutes in 1 hour) = 1200 gallons. Now we can determine the time taken to empty the 15,000 gallons by dividing the total gallons to be emptied by the number of gallons emptied in 1 hour to get 15, 000 ÷1,200 = 12.5 hours.

This is a volume equals rate times time, where gallon is the volume unit and minite is the time unit. Let V be the volume of water required to fill the pool, R be the rate in gallons per minute, and t be the time needed to fill the pool. We have that R * t = V, or t = V/ R. If R = 20 gal/min avd V= 15000 gal, then t = 12.5 hours.

Did that in my head in about 30 seconds. This kind of maths problem was final year primary school standard in my day

Thank you!

15000 gallons at 20 gallons per minute = 750 minutes , divided by 60 = 12.5 hours

Thanks

(20 gal / min) * ( 60 min / hr ) = 1200 gal / hr so 15000 gal = ( 1200 gal / hr ) * x x = 15000 gal * ( 1 hr / 1200 gal ) x = 15000 / 1200 x = 12.5

I'll rain on the parade and just point out that the pump rating is just that. Factors not included here are head, distance and resistance It becomes an engineering question and without all the required information the answer should probably read - no less than 12.5hrs maybe remove the "rated at" part as you wouldn't use that in car over time and distance equation.

By the way, ratio should work too.

The way I did it was: 15,000gals./20gals./60mins.=12.5hrs. Thanks

this problem is a lead into chemistry and similar so you are cancelling units as you transfer to the result you are looking so i wont answer it....

gals/h :20x60=1200 15000/1200=12,5 Answer:12.5 h (took less than half a minute to find the answer.)

Let x be the minutes that the pump will empty a 15000 gallons of water. 20x = 15000 20x/20 = 15000/20 x = 750 Now, reread the question. "How many hours will it take to empty the pool" Since x is in minutes, we shall convert this into hour. There are 60 min in an hour. So the equation should look like this: 60x = 750 x = 750/60 x = 75/6 x = 25/2 Hence, it will take the pump 25/2 hours to complete its job.

Why all the BS. Just divide 15000 by 20X60 much simpler.

5 out of 4 people are bad at math.

Our siblings attended a primary school in Baviaans, all grades in one room, had to do arithmetic no "math" seems as if it is all in the name .

It took to me less than 30 secs to find the 12,5 hours and the teacher here needed 19,27 minutes. What is this????????????????????????????????

Ez concept, poor teacher AGAIN!
