    You are not adding up the total of the syringe values, you are adding up the differences between them.

    From minute 0 to minute 1, it used 0.03cm^3 of oxygen, minute 1 to minute 2 it's 0.02cm^3, etc. From there you should be able to find the answer as it's just a bit of multiplication and division to find the rate as defined in the question.
