,it is a ship docks at the port on 5 different days at 11: 15 am, 9: 45 am, 11: 45 am, 7: 45 am and 10: 45 am. the average time it docks is __: __ am.

Convert the timing into hours only:
11:15  = 11.25h
 9:45  = 9.75h
11:45 = 11.75h
 7:45  = 7.75h
10:45 = 10.75h

To find the average, we need to find the middle of these timing:
11.25 + 9.75 + 11.75 + 7.75 + 10.75 = 51.25

51.25 ÷ 5 = 10.25h = 10:15 am


The average time it docks is 10:15 am.
