Step-by-step explanation:

The first phase of the journey is f. This is where the truck travel for 4 minutes before reaching the gas station. The slope is positive because as time is increasing, distance covered is also increasing.

The truck stopped at the gas station for 2 minutes. This portion of the graph has a zero slope because as time increases, distance covered is constant.

The slope of the last portion of the graph is negative because as the time increases distance decreases as the truck returns to the factory.

See attachment for graph.

Note that the journey took a total of 10 minutes.
