The given line graph compares four American car producers in terms of average time spent producing a vehicle from 1998 to 2005.
Overall, it is clear that the amount of time spent by each manufacturer to produce cars decreased over time, and General Motor suffered the greatest drop compared to four companies.
According to the chart, in 1998, 32 hours were spent to produce vehicles by General Motor. This amount gradually decreased to about 25 hours by 2002. After remaining somewhat stable until 2004, it reached 22 hours in 2005. However, the average time consumed by Ford’s company, started at 28 hours in 1998, grew to a peak of 31 hours by 2001, then it declined steadily to roughly 21 hours by end of the period.
It can be seen that both Toyota and Honda recorded the same hours in certain years throughout the period. In 1998, both manufacturers reported 22 hours per vehicle. After fluctuating over the next three years, they reached the previous value in 2001. The time increased to 24 hours by 2002, but then decreased to 20 hours in 2005.
