Draw a distance-time graph for the journey described in ITEM 4.

Here is the distance-time graph illustrating the journey described in ITEM 4.

ITEM 4: Distance-Time Graph

The graph shows the distance covered over time, based on the following segments:

• From $(0, 0)$ to $(2, 100)$: Driving at $50 \text{ kmh}^{-1}$.
• From $(2, 100)$ to $(3, 100)$: Resting for 1 hour.
• From $(3, 100)$ to $(4.5, 170)$: Driving another $70 \text{ km}$ in 1.5 hours.
