As given by the question

There are given that the survey of 7 students:

$6,\text{ 5, 16, 3, 12, 15, 8}$

Now,

From the formula to find the mean:

$\operatorname{mean}=\frac{\text{Addition of the total given data}}{\text{Total number of data}}$

Then,

$\operatorname{mean}=(6+5+16+3+12+15+8)/(7)$

Then,

$\begin{gathered} \operatorname{mean}=(6+5+16+3+12+15+8)/(7) \\ \operatorname{mean}=(65)/(7) \\ \operatorname{mean}=9.3 \end{gathered}$

Hence, the mean travel time is 9.3 minutes
