Answer:
8.3 L/s
Step-by-step explanation:
To find the answer you need to find the slope also known as the rate of change. When you find slope it is always change in y over change in x.
![\frac{399-150}{40-10}](https://tex.z-dn.net/?f=%5Cfrac%7B399-150%7D%7B40-10%7D)
Then simplify
![\frac{249}{30}](https://tex.z-dn.net/?f=%5Cfrac%7B249%7D%7B30%7D)
Then divide to get your slope/average rate of change
= 8.3
