Answer:
8 hours 20 minutes
Step-by-step explanation:
Given that :
Time Rachel left for school = 7:45 a.m
Time she returned Home = 4:05 p.m
Time for which Rachael was gone :
4:05 p.m - 7:45 a.m
7:45 a.m to 3:45 p.m= 8 hours
3:45pm to 4:05 pm = 20 minutes
= 8 hours 20 minutes
Rachael was gone for 8 hours 20 minutes
There are 12 possible arrangements.
------------------------
- Considering that the blue cup has to be on one end, we consider the number of arrangements possible with the other 4 cups, then multiply by 2(considering the blue on each end).
------------------------
- Considering green and yellow before red and purple, there are
outcomes(G-Y-R-P, G-Y-P-R, Y-G-R-P and Y-G-P-R). - Another two possible outcomes are yellow-purple and green-red, or vice-versa, thus 4 + 2 = 6 outcomes.
- To account for the blue on the end, multiplying by 2.

- There are 12 possible arrangements.
