Apipe delivers 9 liters of water in 20 seconds
(a) find the amount of water it delivere
per minute.
(b) an empty fish tank is 60 centimeters
long. 45 centimeters wide and 30
centimeters high. how many minutes
does it take for the pipe to fill the
empty tank completely with water?
(1 liter = 1,000 cubic centimeters)

a) 27 liters

b)

Step-by-step explanation:

a) =

To get from 20 to 60, you need to multiply by three. And to get the amount of water it fills per minute, you also need to multiply the numerator by 3. 9*3=27.

It fills 27 liters of water per minute.

b) Let's find the volume first.

V=length*width*height

V=60*45*30=81000 cubic centimeters

That means, converting cubic centimeters to liters, you'll get 81000/1000 which is 81 liters to fill.

81/27=3 minutes.
