A cylindrical water tank can be filled to a depth of 2.8m by a pipe A in 2 hours.

      

A cylindrical water tank can be filled to a depth of 2.8m by a pipe A in 2 hours. Pipe B takes 8 hours to fill the tank to the same depth. Pipe C can empty this amount in 6 hours.

a) Starting with tank empty and pipe A running alone in one hour, find the depth of water it fills.

b) If pipe A is turned off and pipe C left open for one hour, what will be the new depth of water?

c) If the tank is initially empty and pipe A and B are both running while pipe C is left open, after how long will the depth of water reach 2m?
