Question 1036337
One pipe can fill a tank three times faster than the other pipe.If together the two pipes can fill the tank in 36 mins,then the slower pipe alone will be able to fill the tank in how many mins?
------------
3 times faster = 4 times as fast
--
The faster pipe takes t minutes, the slower 4t to fill the tank
---
Filling the tank in t minutes --> 1/t tanks per minute flow rate.
In 4t minutes --> 1/4t tanks/minute
---
Together they feel 1/t + 1/4t per minute = 5/4t tanks per minute
5/4t tanks/minute = 4t/5 minutes per tank
4t/5 = 36
4t = 180
t = 45 minutes
--------------
4t = 180 minutes
