Pipe A fills the tank at a rate of 2/5 tank per 60 min.
Pipe B fills at 3/5 tank per 60 min.
So pipe C `emptied it at 1/5 tank per 60 min.
Pipes A and C fill it at a rate of 2/5 - 1/5 = 1/5 tank per 60 min which would be 1 tank per 300 min.

if " 5 " somethings require 60 minutes then " 1 " somethings would require 300 minutes
