A car travels at a constant speed of \(120 \text{ km}{\cdot}\text{h}^{-1}\) for 9 minutes. Over the next 2
minutes, it reduces its speed at a steady rate until it reaches a speed of \(60 \text{
km}{\cdot}\text{h}^{-1}\). The car travels at \(60 \text{ km}{\cdot}\text{h}^{-1}\) for 4 minutes. Over the
next 1 minute, it reduces its speed at a steady rate and comes to a complete stop.
