Working time - shortening

The media often speculates about the change (especially to shorten) the working time of the five-day eight-hour working week to another working model. Calculate how many hours a day the employee would have to work a day at 3-day work week if he must work the same number of hours weekly.

Result

h = 13:20 h Wrong answer

Solution:

5 8=3 h h=(5 8/3)=40313.3333=13.33333=13:20  h 5 \cdot \ 8 = 3 \cdot \ h \ \\ h = (5 \cdot \ 8/3) = \dfrac{ 40 }{ 3 } \doteq 13.3333 = 13.33333 = 13:20 \ \text{ h }
