12 Moons

Good Marry came to ask the twelve Moons for strawberries. All twelve Moons would have picked 1200 strawberries in 20 minutes. However, in 5 minutes the lazy holiday Moons - July and August stopped picking. How many minutes in total will it take collect strawberries?

Correct answer:

t =  23 min

Step-by-step explanation:


1200 = 1200/(12·20)·(10t+2·5)

1200 = 1200/(12·20)·(10·t+2·5)

50t = 1150


t = 1150/50 = 23

t = 23
