  2. 9 hours is incorrect. This is a geometric progression. If we treat the volume entering the container in the first hour as 1 unit, then in 10 hours a total of 1,023 units will enter the container. 512 of these units will enter the container in the final hour, leaving 511 units in the first 9 hours. 511 is not half of 1,023.
