How high was the plane when the decoy was released and how long was the decoy in the air?

First I fount the velocity components:

v(0,x)=250cos(-30)=216.5 m/s

v(0,y)=250sin(-30)=-125 m/s

Then I used this equation:

y=tan(theta)x-(gx^2)/(2(v(0)cos(theta))^2)

I got 455.36 meters, but I'm told that it is wrong. What am I doing incorrectly?
