Answer :
Final answer:
It will take 8 pipes of the same size to fill the tank in 128 minutes.
Explanation:
To solve this problem, we can set up a proportion using the number of pipes and the time taken to fill the tank:
5 pipes : 80 minutes = 8 pipes : x minutes
We can cross-multiply and solve for x:
5x = 8 * 80
5x = 640
x = 640 / 5
x = 128
Therefore, it will take 8 pipes of the same size to fill the tank in 128 minutes.
