    Thanks KSTEC for your post. That does make sense, but with the second problem, I saw that the answer wasn't correct. Answer should have been 113, but yours was 120ml/hr. I think I will probably stick with the first method that melody in my heart had. Just seems easier to me, and we know that is what you have to do when you get out on your own.

    The second questioned ask per min not per hour which does come out to 1.875ml/min or 112.5/hr. Because I'm a LPN and do not do program IV's pumps I just rounded up to 2ml/min. Thanks for you input, I've always wonder if my method was easy or hard.

    This is a perfect example of the concept of rounding error. Don't round until you have your final answer. If you round your intermediates, you will have more error in your answer.
