[tex]1 \frac{2}{3} + 2 \frac{1}{3} + 2 \frac{2}{3} = [/tex]

[tex] \frac{3*1+2}{3} + \frac{3*2+1}{3} + \frac{3*2+2}{3} =[/tex]

[tex] \frac{3+2}{3} + \frac{6+1}{3} + \frac{6+2}{3} =[/tex]

[tex] \frac{5}{3} + \frac{7}{3} + \frac{8}{3} =[/tex]

[tex]= \frac{20}{3} h[/tex]

In hours:

20 |_3
(2)....6hs
x60' 
------
120' |_3
(0)....40' 

Answer:
6hs40min

or

[tex] \frac{20}{3} hs = \frac{20}{3} *60' = \frac{1200}{3} = 400'[/tex]

400' = 6*60' = 360' + 40' = 400' (True)
Until

6hs40min
