Squids rely on jet propulsion to move around. A 1.3kg squid drifting at 0.48m/s

Question

Squids rely on jet propulsion to move around. A 1.3kg squid drifting at 0.48m/s suddenly expels 0.11kg of water backward to quickly get itself moving forward at 2.4m/s . Notice that the water is inside the squid's body before it is squirted out. If drag is ignored over the small interval of time needed to expel the water (the impulse approximation), with what speed relative to its pre-ejection speed (not relative to the ground, that answer is not a useful one for the squid) does the squid eject the water?
