The flight is just over an hour long in actual time (remember that Melbourne is half an hour ahead of Adelaide's time.)
There is half an hour's time difference between Melbourne, which is in the state of Victoria, and the state of South Australia. Melbourne is ahead by 30 minutes, meaning that, when it is 12:00 in Melbourne, it is 11:30 in Adelaide.

The driving distance between Melbourne and Adelaide is 725km (450 miles), and the journey takes around 9 hours to travel, without breaks. It is a full day's journey.
I believe it has something to do with the general wind direction. It tends, as far as I know, to progress from west to east, so when a plane is flying west (to Melbourne), the plane is flying against the wind, and will take longer. When the plane is flying east (i.e. from Adelaide to Melbourne), it is flying with the wind and thus doesn't take as long. The same thing occurs flying from Melbourne to New Zealand - it takes less time to reach New Zealand than it does to return - the difference being roughly an hour.
Whether travelling by bus or car, the shortest route between Melbourne and Adelaide is via the Western Highway, at 725 km, or 450 miles.The time spent on the bus journey is around 10.5 hours.
