The following are simulated depth vs. clock time data for the flow experiment:
| clock t | 4.2 | 8.4 | 12.6 | 16.8 | 21 | 25.2 |
| depth | 80.2 | 72.9 | 67.5 | 63.3 | 59.3 | 55 |
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.
