Answer:

9 days

Step-by-step explanation:

He sets his watch 12 seconds behind

For every day that passes it falls back another 1 second

So once it is 21 seconds behind all you have to do is subtraction to find the amount of days past

21 - 12 = 9

Since its 12 seconds behind already itll take 9 days to be behind 9 more seconds.
