Answer 1

The total number of students is 7.

To find the mean you must add all the numbers in the list given and then divide the sum by the total of the numbers.

The sum of all the numbers.

`\begin{gathered} 16+11+10+12+16+13+9 \\ 87 \end{gathered}`

Next divide 87 by 7.

`(87)/(7)=12.42`

So, the mean of their travel time is 12.4 (rounded to the nearest tenth)
