The bar chart illustrates the average time commuters in four Australian cities—Sydney, Brisbane, Perth, and Adelaide—spent traveling to work from 2002 to 2010.
Overall, commuting times generally increased in all cities, with Sydney recording the highest durations, while Adelaide maintained the lowest, despite fluctuations.
In Sydney, the average time rose steadily from 30 minutes in 2002 to 38 minutes in 2010. Brisbane showed a consistent biennial increase, from 22 minutes to 30 minutes over the same period. Perth experienced slight variation, dipping from 18 to 17 minutes in 2004 before rising to 21 minutes by 2010.
In contrast, Adelaide displayed the most fluctuation. It began at 24 minutes, increased to 27 minutes in 2006, then reached 30 minutes in 2010, despite not following a linear trend.
In summary, Sydney and Brisbane saw steady increases, Perth’s rise was delayed and moderate, while Adelaide’s commuting times were irregular but ended at the same level as Brisbane.
