Let's solve 
Divide both sides by 100:
Take the square root of both sides:
(I did not keep the negative value because it doesn't matter since we are only considering even powers of 
.)
So now let's plug it into:
X=time of the third person it would take to fill the pool
We can suggest this equation:
6[(1/20) + (1/15) +(1/x)]=1
6[(3x+4x+60)/60x]=1
(7x+60)/10x=1
7x+60=10x
7x-10x=-60
-3x=-60
x=-60/-3
x=20
Answer: the third person alone would fill the pool in 20 hours .
