It takes a smaller hose times as long to fill a certain swimming pool as it does a larger hose. It takes both hoses working together minutes to fill the pool. How long will it take the larger hose to fill the pool by itself?

25 mins

Step-by-step explanation:

I think your question is lack of information, and here is my addition for it:

It takes a smaller hose  4  times as long to fill a small swimming pool as it does a larger hose. It takes both hoses working together  20  minutes to fill the swimming pool. How long will it take the smaller hose to fill the pool by itself?

My

Let x the time of the Larger hose so the time of the small hose is: 4x

It takes both hoses working together  20  minutes to fill the swimming pool. which mean:

<=> x = 20 +5 = 25 mins

and the time of the small hose is 4*25 = 100 mins
