Answer
The mean travel time is 11.9 minutes.
Solution
1. Calculate the sum of the travel times:
\[
13 + 15 + 10 + 8 + 12 + 16 + 10 + 11 = 95
\]
2. Determine the number of students, which is \(8\).
3. Compute the mean travel time:
\[
\text{Mean} = \frac{95}{8} = 11.875
\]
4. Round the mean to the nearest tenth:
\[
11.875 \approx 11.9
\]
Thus, the mean travel time for these students is \(11.9\) minutes.

To find the mean travel time, add up all the minutes: \( 13 + 15 + 10 + 8 + 12 + 16 + 10 + 11 = 95 \) minutes. Then, divide this total by the number of students: \( 95 \div 8 = 11.875 \). Rounding to the nearest tenth, the mean travel time is \( 11.9 \) minutes. \( \boxed{11.9} \) minutes
