Problema Solution
A swimming pool can be filled in 18 hours if water entering through a pipe alone or 23 hours if water enters through a hose alone. If water entering through both the pipe and the hose how long will it take to fill the pool?
Answer provided by our tutors
let 'x' represent the number of hours that pipe and the hose need to fill the pool together
1/18 + 1/23 = 1/x
by solving we find:
x = 10 4/41 hr
click here to see the step by step solution of the equation:
4/41 hr = (4/41)*60 min = 5.85 min
it will take 10 hour 5.85 min for the hose and the pipe to fill the pool together.
