Calculate total flow from flow rates?

Hi all,
I think this is probably an easy one, but I'm just not getting something.

Let's say that I have a series of volumetric flow rates (liters per minute):

10 l/min at 7:00
20 l/min at 8:00
15 l/min at 9:00

Now for each of these intervals, I want to estimate the total flow in
liters.

How much flowed between 7:00 & 8:00?

How much flowed between 8:00 & 9:00?

I think I need to use the slope (rate of change) in the calc, but I don't
know how.
For simplicity sake, I'll consider it linear. In reality, it's a curve, but
I'd like to increase my chances of getting an answer :-)

Ideally, I'd like to see both solutions, but the simplest one would help me
out tremendouly for the time being.



Thanks!!!!
