The given table illustrates the data of average distance travelled yearly, in miles, from various means of transportation by adults in 1977 and 2007.
Overall, it is apparent that while the annual mileage covered by four-wheel vehicles and train experienced a rise, there was a drop recorded in bus, walking and twin wheel transportation. In addition, cars was the most preferable when travelling long distance by adults in both of the periods shown.
To begin with, the annual mileage for cars held the highest of 3500 miles in 1997, after which the figure soared to 7100 miles, which was almost a twofold increase. The same pattern can be seen in taxi, averaging at 200 and a quadruple in 1997 and 2007 respectively. Trains were also favoured by adults for commuting abeit only a marginal growth, with 900 miles in 1997 and 1000 miles in the following decade.
A reverse trajectory can be seen in the remaining figures. The annual mileage of bus had encountered a decrease from 800 miles in 1997 to just 500 in 2007. Bicycles and motorbikes shared the same data for yearly commuting distance of a hundred miles in 1997. After that, the former went down by 20 miles while it was 10 miles for the latter in a decade. Furthermore, adults engaging in walking with the figure of 400 miles in 1997, the activity had become less popular in 2007 with a drop of a hundred miles.
