A group of people were surveyed, asking them to report the number of
miles they drive to work. Those people were divided into five different
groups. The mean number of miles that the people in each group drive to
work is given in the table below. For example, in the group containing 16
people, the mean number of miles those 16 people drive to work is 24.
What is the mean number of miles that all of the surveyed people drive to
work? If needed, round your answer to the nearest whole number.
