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 (2)/(3) + 2 (1)/(3) + 2 (2)/(3) =`


`(3*1+2)/(3) + (3*2+1)/(3) + (3*2+2)/(3) =`


`(3+2)/(3) + (6+1)/(3) + (6+2)/(3) =`


`(5)/(3) + (7)/(3) + (8)/(3) =`


`= (20)/(3) h`

In hours:

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

Answer:
6hs40min

or


`(20)/(3) hs = (20)/(3) *60' = (1200)/(3) = 400'`

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

6hs40min
