During an airport turnaround, a baggage tug moves between two loading areas and is stationary while a trailer is coupled.
| Part of the operation | Distance travelled / m | Time taken / s |
|---|---|---|
| First moving section | 120 | 30 |
| Second moving section | 180 | 45 |
The average speed of the tug for the complete operation, including the time spent stationary, is 3.0 m/s.
What is the time for which the tug is stationary?
