John jr. can construct 180 boxes in an hour. john sr. can only construct 20 boxes in an hour. working together, how many minutes will it take them to construct 600 boxes?

180 Minutes

Step-by-step explanation:

in one hour Jr. will make 180 and Sr. will make 20. so in one hour they will make 180+20=200

200*x=600

x=3

so 3 hours

1 hour has 60 minutes

1hr=60*3=180 Minutes

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;
