14x. ....................
Um... it'll take each pipe 80 mins, bcz if together they take that long, then to find the pipes time separately, you just multiply it by two to show it doing the work the other pipe did as well. Is that what you wanted??
4,400 + 17,600 = 22,000.
4,400 / 22,000 = 0.2
0.2 = 20%
The answer is A.
Hope this helped☺☺
