three pumps of the same capacity can fill a swimming pool in 15hrs. how long will it take for 5 pumps of the same capacity to fill the pool
-------
The time is inversely related to the number of pumps used.
---
t = k/p
----
Solve for "k" using "three pumps of the same capacity can fill a swimming pool in 15hrs"
-------
15 = k/3
k = 3*15 = 45
------
Equation:
t = 45/p
-------------
"How long will it take for 5 pumps of the same capacity to fill the pool"?
Using the equation you get:
t = 45/5 = 9 hrs.
