Question

Ivan biked 1 whole 2/3 on Monday, 2 wholes 1/3 hours on Tuesday, and 2 wholes 2/3 on Wednesday. What is the total number of hours Ivan spent biking?

Answer 1

$1 \frac{2}{3} + 2 \frac{1}{3} + 2 \frac{2}{3} =$

$\frac{3*1+2}{3} + \frac{3*2+1}{3} + \frac{3*2+2}{3} =$

$\frac{3+2}{3} + \frac{6+1}{3} + \frac{6+2}{3} =$

$\frac{5}{3} + \frac{7}{3} + \frac{8}{3} =$

$= \frac{20}{3} h$

In hours:

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

Answer:
6hs40min

or

$\frac{20}{3} hs = \frac{20}{3} *60' = \frac{1200}{3} = 400'$

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

6hs40min
