Answer:
3.6 hours or 3 hours and 36 minutes.
Step-by-step explanation:
If the first pipe can fill the pool in 9 hours that means that in 1 hour it fills
of the pool, we use the same logic for the second pipe and conclude that in 1 hour it feels up
of the pool. If both were to fill the pool together that means that in 1 hour they would fill...
of the pool in 1 hour.
Now to find how many hours it will take divide the pool by the speed with which it is getting filled.
hours
3.6 hours in other words is 3 hours and 36 minutes.
I don’t know what the equation is but when using elimination you should cancel out opposite numbers such as 4x and negative 4x
