Bike: 120 miles, about 7.5 hours a week.
Car: 15 miles, about 30 minutes a week (taking kid to before-school band practice, taking garbage and recycling to the transfer station on Saturday, occasional short errands).
Walk: Occasionally will walk to church instead of riding, that's about 30 minutes once a week (a mile there and back) Not counting walking around inside or just within my own property to do garden work on weekends.

Any other mode: zero. no trains or busses around here, haven't flown anywhere in years.
