The following are simulated depth vs. clock time data for the flow experiment:
| clock t | 6.5 | 13 | 19.5 | 26 | 32.5 | 39 |
| depth | 57.8 | 50.2 | 43.6 | 38.7 | 34.8 | 31.7 |
Clock times are in seconds, depths in cm.
Using a graph and simulaneous linear equations find a model for this data set and compare your model with the data.
