An oceanographer investigates the power output of three different automated winch systems, Alpha, Beta, and Gamma, used to retrieve scientific sensor probes from the seabed. The operational data for each retrieval is recorded in the table below.
| Winch System | Tension in N | Distance in m | Work done in J | Time taken in s | Power in W |
|---|---|---|---|---|---|
| Alpha | 29.0 | 25.0 | 725.0 | 10.0 | 72.5 |
| Beta | 25.0 | 1020.0 | 15.0 | 68.0 | |
| Gamma | 25.4 | 25.0 | 635.0 | 63.5 |
Use the data for all three systems to calculate their average power.
