The pelican and the fish were rising up with a velocity of 0.22 m/s just before the instant it was dropped.
So initial velocity of the fish is 0.22 m/s upwards.
Accl. is g(=9.8m/s^2) downwards.
Use equations of motion in a straight line to solve.

v=u+at
Considering upward to be negative,
v= -0.22+9.8*.33

In .33 seconds, the fish falls by
s= -0.22*0.33+0.5*9.8*.33^2 m
Pelican rises by 0.22*0.33 m
Add the distances to get the answer
