Question 11 Working together, it takes two different sized hoses minutes to fill a small swimming pool. If it takes minutes for the larger hose to fill the swimming pool by itself, how long will it take the smaller hose to fill the pool on its own?

x = 12 hrs to fill the pool

Step-by-step explanation: INCOMPLETE QUESTION

Missed information:

Time for two different sizes hoses to fill a small simming pool (let say that is 3 hours)

Time for one of the two hoses to fill a small simming pool ( lt say that is 4 hours)

With that information we can answer the question

If one of the hoses fill the pool in 4 hours, it will fill 1/4 of the pool in 1 hour

We dont know the other hose how long it take to fill the pool so let call that time x hours then in 1 hour it will fill 1/x of the pool

In 1 Hour the two hoses will fill 1/3 of the pool then

In one hour

1/4 + 1/x = 1/3     Solving for x

( x + 4 )/ 4x  = 1/3

3x + 12 = 4x

- x  = -12       x  = 12 hours

did you get the answer?

i think it is d. hope this
