All the possible arrangements are:
When Bob is in the first place
B A C X X
B A X C X
B A X X C
B X A C X
B X A X C
B X X A C
6 possible arrangements
When Bob is in the second place (notice that neither Alice nor Cindy can be before Bob)
X B A C X
X B A X C
X B X A C
3 possible arrangements
When Bob is in the third place
X X B A C
Only 1 possible arrangement.

Answer:
6 7/12 hours in June
Step-by-step explanation:
Find the answer to this question by subtracting 6 4/6 hours from the total 13 1/4 hours:
13 1/4 hours is equivalent to 12 5/4 hours (we borrow '1' from 13 1/4).
Thus, we have
12 5/4 hours Note that the LCD of 5/4 and 4/6 is 12. Thus
- 6 4/6 hours we have
12 15/12 hours
- 6 8/12 hours
