The answer is 30 minutes.

Step-by-step explanation:

The average or mean is determined by finding the sum of all of the given values and dividing that by the length of the data set. In this case, three values are given.

By adding 28 + 31 + 31, you get that this is equivalent to 90.

The sum is then divided by the number of values in the data set.

Therefore, 90 minutes / 3 values is equivalent to 30 minutes.
