12 Moons

Good Marry came to ask twelve moons for help with collecting strawberries. All twelve moons 1200 strawberries picked in 20 minutes. But lazy months July and August cease tear after 5 minutes. How many minutes in total will take collect strawberries?

Result

t =  23 min

Solution:


1200 = 1200/(12*20)*(10t+2*5)

50t = 1150

t = 23

Calculated by our simple equation calculator.
