It will take Anthony 75 minutes to complete the entire group of 180 place cards.
To solve this problem, we can set up a proportion:
12 place cards / 5 minutes = 180 place cards / x minutes
Cross-multiplying, we get:
12x = 900
Dividing both sides by 12, we get:
x = 75
Therefore, it will take Anthony 75 minutes to complete the entire group of 180 place cards.
