Problema Solution
One pipe can fill a tank in 30 minutes, but a second pipe can fill it in 25 minutes. How long will it take if both pipes are used?
Answer provided by our tutors
The time taken if both pipes are used is x
So the equation is x
1/20 + 1/25 = 1/x
So
x = 100/9 min = 11.1 min
So The time taken if both pipes are used is 100/9 min = 11.1 min
