In Century Park, there is a large meadow that grows a lot of weeds every day (assume the number of weeds that grow per minute is constant). Every morning at 8:00 AM, some workers go to remove the weeds (each worker removes weeds at the same rate). Once all the weeds are removed (the number of weeds is 0, with no good grass being removed), the workers stop, and any new weeds that grow afterward are left for the next day. 

On the first day, some workers started removing weeds and finished by 9:00 AM. On the second day, 10 workers removed weeds and finished at 8:30 AM. On the third day, 8 workers removed weeds and finished at an integer minute. What is the integer minute they finished, rounded to the nearest minute?
