The sum would be 4x^2 + 4x + 3.
To find the answer you would add like terms together.

X^2 + x + 1 + 3x^2 + 3x + 2. Just combine the like terms:

x^2 + 3x^2 + x + 3x + 1 + 2

4x^2 + 4x + 3. <--- the sum.

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

------------------------------------------------------------------------
Answer: The average time it docks is 10:15 am.
