Now then. The bathtub holds 100 gallons.
1:06:36

"A" fills it at the rate of 20 gallons a minute,
1:06:42

and "B" at the rate of ten gallons a minute.
1:06:46

- Got that, Mr Morgan?

- Twenty and ten gallons. Yes, sir.
1:06:50

Now then. "C" is a hole that empties it

at the rate of five gallons a minute.
1:06:56

How long to fill the tub?
1:07:04

There is silly. Trying to fill

a bathtub full of holes, indeed.
1:07:09

A sum it is, girl. A sum.

A problem for the mind.
1:07:13

- For his examination into school.

- That old national school.
1:07:16

'Tis silly they are with their sums. Who

would pour water in a bathtub full of holes?
1:07:21

- Who would think of it? Only a madman.

- It is to see if the boy can calculate.
1:07:25

Figures, nothing else.

How many gallons, and how long.
1:07:29

In a bathtub full of holes.
1:07:34

Now I know why I have such a tribe of sons.
1:07:37

It is you, Beth Morgan, is the cause.
1:07:40

Look you, Mr Gruffydd.

Have you something else?
1:07:43

The decimal point.
1:07:47

The decimal...
1:07:50

The decimal point, then,

and peace to my house.
1:07:53

- Go and scratch.

- Well, it's getting late.
1:07:56

I've got to get along. We'll follow

the decimal point tomorrow night.
