    Riemann Sums question?

    I'm pretty sure about my answer to this question, but can you check it? (It's just a practice quiz, for participation points, but I want to know if I have it right)

    I would be confident about my answer, but it worries me that it is the only one with the "thousand" option. Am I right?

    You have posted several questions with what you hope is the answer, but not how you got to that answer. You will gain confidence (and we will gain knowledge that you aren't just hoping we'll do the work for you) if you post what you have tried to GET those answers...

    Gosh, I'm sorry. It just takes so long to type in my work. Okay so when I graphed this out and took the right hand points*2 (the width) it gave me 43.8. I can attach an online graph of the points to show my work? It'll have to be in a couple hours though because I have classes. The thing is I'm almost positive it's 43.8 but I'm not sure if the "thousands" part is right, because the wording of the question is tricky. What do you think? And I'll post the graph as soon as I can.

    The flow rate is in thousands of gallons per hour, and the time is in minutes, so assuming your 43.8 is correct, you need to divide by 60, which gives 730 gallons.
