Depends but generally:
Run 45-50(generally 5-6 runs), with a long run of 12+, an AT and a Brick/Speed Workout
Bike: 4-5 rides: a 2x25-35mi(complments the running speed workout above), 30-40mi, 40-50mi and a long ride
Swim: 3-4 times per week. 1 or 2 of 1200 meters. One of 1500-2000 and one long swim of 2500 or so.
Somewhere around 15 hours a week I suppose.
