Answer:
[tex]v=\frac{d}{t}[/tex]
Explanation:
The average velocity of a moving object is given by:
[tex]v=\frac{d}{t}[/tex]
where
d is the displacement of the object
t is the time taken
In this problem, we have
d = 25 m is the displacement
t = 2 s is the time
Therefore, the average velocity of the seagull is
[tex]v=\frac{25 m}{2 s}=12.5 m/s[/tex]
Note that velocity is a vector, so it has not only a magnitude, but also a direction, which corresponds to the direction of the displacement (downward, in this example).
