Take the middle value of each category.
For example :
For the category of 0 ≤ t ≤ 10,
Take 5s.
So total time for this category
= 5 s per student x 6 students
= 30 s.
Do the same steps for each of the other
categories.
Then add up the time for all the categories.
Then divide it by the total number of students.
