With a good diet and 1 hour of excersises 5 times a week, how long does it take to get a six-pack??

Summer is near, and the perfect thing to go with it is a strong, six-pack stomach.
Im male, 17. Im starting a 90% vegan diet (%10 meat,fish,chicken) and drinking water ONLY. No junk food, fast food, soft drinks, or excess fats or sugars.
Im going to the gym 1 hour (sometimes 1.5), 5 times a week (Mon.-Fri.). I do everything from spinning, weightlifting, abs & push-ups, etc.
Im also planning to run from 30 min. to 1 hour every morning before breakfast.
If i follow this routine, aprox. how long woill it take me to see results (see a six-pack)?

Im skinny, but got no muscle. Im 1.75 m tall. There is a thin layer of fat covering my abs, so I know I have ot get rid of that first.
