The following are simulated depth vs. clock time data for the flow experiment:
| clock t | 3.5 | 7 | 10.5 | 14 | 17.5 | 21 |
| depth | 70.6 | 67 | 63.9 | 60.5 | 58.6 | 56.9 |
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.
