There are five sections of line on the graph. From the origin, the first section of the line is increasing in both time and distance. This means Mr. Wong is driving his vehicle.
The second section shows an increase in time but not distance. This means Mr. Wong stopped for some time.
The third section shows an increase in both time and distance. Again, Mr. Wong is driving his vehicle.
