For sample adults who had participated in biking in the past 2 weeks (EXBIKE), EXBIKEMIN reports the average number of minutes respondents had spent biking each time they had engaged in that activity over the past 2 weeks.

After determining that a respondent participated in biking, respondents were first asked, "How many times in the past 2 weeks did you bike?" (EXBIKENO). They were then asked, "On the average, about how many minutes did you spend biking each time?" EXBIKEMIN reports the answer to this last question.
