    The median is when you line up the numbers from least to greatest and find the middle number:

    8, 8, 9, 9, 10, 12

    Since there is an even number of numbers, we take the two middle numbers and find the mean of them: (9 + 9) / 2 = 9.

    So, the median is 9.

    The mean is when you add all the numbers up and divide that by the number of numbers:

    (8 + 8 + 9 + 9 + 10 + 12) / 6 = 56/6 which is about 9.3.

    The median is 9 minutes, and the mean is about 9.3 minutes.
