A small pool is being drained. There are 1,320 gallons of water remaining in the pool after 2
minutes and 1,040 gallons after 9
minutes. How long would it take for the pool to be completely drained?(1 point)
minutes
The pool is losing (1,320-1,040) = <<1320-1040=280>>280 gallons every 2 minutes.
To completely drain the pool it will take 280/2 = <<280/2=140>>140 sets of 2 minutes.
So, it would take 140*2 = <<140*2=280>>280 minutes for the pool to be completely drained. Answer: \boxed{280}.
