Answer provided by our tutors
we assume this question is asking for the amount of time to fill the pool with water flowing through both the pipe and the hose
let 'x' represent the amount of time it takes to fill the pool with water flowing through both the pipe and the hose:
1/x = 1/18 + 1/23
solving for 'x' we have x=10.097
it will take approximately 10.1 hours
