The following are simulated depth vs. clock time data for the flow experiment:
| clock t | 3.6 | 7.2 | 10.8 | 14.4 | 18 | 21.6 |
| depth | 75.2 | 70.4 | 65.2 | 61.2 | 57.7 | 55.4 |
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.
