how do i get a six pack in 6 to 9 months?

is there a way or is it impossible and it will take me longer?
im already working out and my body is pretty athletic i do have some fat too but after all the upper body work outs i do some ab workouts but they arent mainly for abs thier mostly for my arms but the extra ab workout is just a bonus, i usually sprinted up and down my alleyway but now i run on the treadmill for a bout 20 minutes for about 2 and a half miles at the gym, what can i do to get a six pack in 6 months minimum, or 9 months maximum
A and B workouts are my upper body days
C workouts are my lowerbody
I do cardio everyday
And i just started this worout

oh yeah i made a bet with my aunt in houston that i could have better defined arms and a six pack by june…yeah…hope i can do it :D
