Final answer:
To find the upper bound for the total distance traveled by all the bicycles in one day, multiply the total number of bicycles by the average distance traveled per bicycle.
Step-by-step explanation:
To find the upper bound for the total distance traveled by all the bicycles in one day, we need to multiply the total number of bicycles by the average distance traveled per bicycle. In this case, the total number of bicycles in Beijing in 2005 was 9 million (rounded to the nearest million) and the average distance traveled by each bicycle was 6.5 km (rounded to one decimal place).
Therefore, the upper bound for the total distance traveled by all the bicycles in one day is approximately 58.5 million km. This is found by multiplying 9 million by 6.5 km.
