The machine

The machine works 7 hours a day and produces 1 part in 5 minutes. How many parts will it produce in 1 hour? How many parts will it produce in 1 day?

Result

n1 =  12
n2 =  84

Solution:

n1=605=12n_{ 1 } = \dfrac{ 60 }{ 5 } = 12
n2=n1 7=12 7=84n_{ 2 } = n_{ 1 } \cdot \ 7 = 12 \cdot \ 7 = 84
