Answer:
11:34 AM
Explanation:
To find out the start time of the water fight, we need to subtract the total time it took from the end time.
End time: 1:08 P.M.
Total time: 1 hour and 13 minutes for water balloons + 21 minutes for hoses = 1 hour and 34 minutes
So, we subtract 1 hour and 34 minutes from 1:08 P.M.
1 hour before 1:08 P.M. is 12:08 P.M.
34 minutes before 12:08 P.M. is 11:34 A.M.
Therefore, the water fight started at 11:34 A.M.
