Two tanks of equal volume are connected in such a way that one tank can be filled by pipe A in 1 hour 20 minutes. Pipe
B can drain one tank in 3hours 36 minutes but pipe C alone can drain both tanks in 9 hours. Calculate:
(a) The fraction of one tank that can be filled by pipe A in one hour.
(b) The fraction of one tank that can be drained by both pipes B and C in one hour.
(c) Pipe A closes automatically once both tanks are filled. Assuming that initially both tanks are empty and all pipes
opened at once, calculate how long it takes before pipe A closes.
