Answer:
time period is 60 hours
Explanation:
given data
inlet pipe = 10 hours
outlet pipe = 12 hours
to find out
With both pipes open, how long will it take to fill the pool
solution
we know here
In one hour [tex]\frac{1}{10}[/tex] of the pool is filled
and in one hour [tex]\frac{1}{12}[/tex] of the pool emptied
we consider time period is x and we apply the equation that is
[tex]\frac{x}{10} - \frac{x}{12}[/tex] = 1
x = 60 hours
so time period is 60 hours
