Problema Solution
A pool can be filled by one pipe in 5 hours and by a second pipe in 2 hours. How long will it take using both pipes?
Answer provided by our tutors
Let 'x' represent how long it takes to fill the pool using both pipes:
1/x=1/5+1/2
x=1.428...
So it would take approximately 1.4 hours, just under 1 1/2 hours.
