How Long Will It Take To Get a 6 Pack?

Hey, I'm 5 " 11, 16 years old, and I weight 151 pounds. I was wondering how long it will take to get a 6 pack? I've got a little bit of belly fat, but i was built quite big. On mondays I go to the gym - 1 hr nd a half, tuesdays I run between 3-7 kms with pushups+situps, wednesday - gym, thursday same as tuesday, and friday - gym, and sunday I play sport. I was wondering how long it would take to lose the remainder of my belly fat and get a 6 pack, what's the best advice that you could give me? At the gym I do cardio, tredmill, bike etc. weights, sit ups, push ups, chin ups, bench press, pec dec, lat pull downs and many others. Thank you :) oh and i've been going to the gym for about 2 weeks now.
