:50:05
Check it again.
:50:08
It should be 250 yuan,
not 2.5 yuan.
:50:12
You missed the decimal point.
:50:23
It's done.
:50:30
Moving 1 0,000 bricks
earns 40 yuan.
:50:34
52 bricks times 1 0,000
divided by 40.
:50:40
That substitute is not bad.
She can teach mathematics, too.
:50:47
1 30,000 bricks?
That many?
:50:49
Sure there isn't an extra zero?
:50:52
We can't move that much.
:50:56
Last time was already hard!
:50:58
Let's calculate the time.
:51:01
Yesterday we moved 1 500 bricks...
:51:04
and it took us 2 hours.
:51:07
If we move 1 30,000...
:51:09
how much time do we need?
:51:11
- I know!
- Come on up.
:51:16
Zhang Mingshan, you calculate.
:51:23
Two hours to move 1500 bricks.
:51:28
How long do we need?
:51:34
1 75 hours.
:51:37
That's too much!
:51:40
If we work eight hours a day...
:51:44
how many days must we work?
:51:49
Twenty-one days.
:51:51
- Twenty-one days and seven hours.
- Twenty-two days.
:51:56
You made a mistake.
:51:58
- I made a mistake.
- Where?
