How to List Time Spent on Extracurriculars on Common App

<p>I know that the common app asks for hours/week and weeks/year. I don't know what to list for some of my activities because the time spent increased as I gained more leadership positions and experience. For example, when I started student government as a Freshman, I only spent an hour or so per week. By junior year, I was spending maybe 7+ hours. How do I list something like that on the common app? Do I write the amount of time I am currently spending when I apply or should I try to average the time spent over the four years?</p>
