If allen worked out for 6 days a week, for 360 minutes last week, and each day was the same amount. Each day he worked out for 60 minutes or 360/6. If he rode his bike for 45 minutes each day, then 60-45=15 or 15 minutes of jogging per day. 15 minutes * 6 days is 90 minutes that week, so the answer is 90 minutes.
