The table presents data about average distance traveled in miles per year for 7 means of transportation in 2 different years (1977 and 2007).
Overall, it could be readily understood that cars contributed the most to the total distance traveled in both years, while bicycles and motorcycles were always at the bottom of the table.
Apparently, people in 2007 took more taxis (800 miles) and fewer buses (500 miles) in contrast to 1977, when it was the other way around.
Car travel distance nearly doubled throughout these years, while train travel only increased by 100 miles, keeping the second place as in 1977.
Surprisingly, walking is not the least used means of transport, although its distance declined 100 miles, while the total average distance increased sharply in these 30 years.
