22.4 minutes

Explanation:

Stem Plots are a combined form of a Histogram and a data chart. They make it easier to extract numeric data from the distribution.

In this case we can visually see the "peak" in times at 22 minutes. The "leaves" indicate that the refined "center" is at 22.4 minutes (take the average of the 8 values).
