Working together, two pipes can fill a swimming pool in 4 hours. Working alone the larger pipe can fill the pool in 6 hours. How many hours would it take the smaller pipe working alone to fill the swimming pool.

12 hours

Step-by-step explanation:

The computation of the number of hours does the smaller pipe takes for working alone is shown below:

Given that

Total time taken for both types is 4 hours

And, the larger pipe alone can take 6 hours

Now for the smaller pipe we assume x

So,

x = 12 hours

c.
