Atank is filled in 3 hours by 3 hoses. hose c is twice as fast as b and b is three times as fast as a. how long will hose a fill an empty tank on its own?
plz write steps

The water tank will be filled up in 10 hours. Solution:
Hose B = 2 (A)
Hose C = 3 (B) ; 3 (2(A)); 6(A)

Equation:
Hours = Hose A+B+C
3 hours = A + (2(A)) + (6(A))
3 hours = 10A
A = 0.3 hours

to get hose A on its own:
A=hours
0.3 = 3 hours
=10 hours

The answer is the numbers between =5 and 5

What the heck i didn’t know
