Using the mean concept, it is found that:
Relative to Sabrina's goal, her average swim time over the last five weeks is 0.1 hours.
-----------------------
The mean of a data-set is given by the <u>sum of all observations divided by the number of observations</u>.
In this problem:

Thus, the mean is:
Relative to Sabrina's goal, her average swim time over the last five weeks is 0.1 hours.
