An airport baggage tug travels along a route without stopping. The table shows the distance of each section of the route and the speed of the tug for the first two sections.
| Section | Distance travelled (m) | Speed (m/s) |
|---|---|---|
| 1 | 200 | 2.0 |
| 2 | 200 | 4.0 |
| 3 | 100 | Not known |
The target average speed for the whole route is 3.0 m/s. The maximum speed of the tug is 5.0 m/s.
Calculate the speed the tug would need to travel at during section 3 to achieve the target average speed.
Justify whether the tug can achieve the target average speed.
