There were already $365$ meatballs.

#### Explanation:

Start off by working out how many meatballs were made in the hour of production.

One hour is $60$ minutes which is $3 \times 20$ minutes.

So, during one hour the number of meatballs made was:
$3 \times 802 = 2 , 406$

That is the same as:

$802 + 802 + 802 = 2 , 406$ for the three periods of $20$ minutes.

But there were then $2771$ meatballs altogether.

$2771 - 2406 = 365$

There were already $365$ meatballs.
