The equation that you want for this is Vf^2 = Vi^2+2(a)*(deltaX)
Vf is your final velocity - in this case 233 m/s.
Vi is you initial velocity - in this case 119 m/s.
a is acceleration - in this case 17.7 m/s^2
deltaX is the change in your x position - what you are trying to find
plug everything in and solve for deltaX and you get 1133.56 m
