Problema Solution
Working together, it takes two different sized hoses
40
minutes to fill a small swimming pool. If it takes
65
minutes for the larger hose to fill the swimming pool by itself, how long will it take the smaller hose to fill the pool on its own?
Answer provided by our tutors
Let 'x' represent the combined time for filling the swimming pool. The combined filling should be solved by expressing ratios:
1/40 + 1/65 = 1/x
x=24.76
So it would take approximately 25 minutes to fill the swimming pool when using both hoses.
