of order. How long will the remaining pumps take to make the tank empty?​

Answer 1

Step-by-step explanation:

24 minutes

Step-by-step explanation:

12 pumps can make water tank empty in 20 minutes

But, 2 pumps are out of order

so,( 12-2=10)

Now 10 pumps can make water tank empty in x minutes .

So 12×20=10 × x

240=10×x

240/10=x

x=240/10

x=24

so, the 10 pumps take 24 minutes to make the tank empty.
