Answer:
The average velocity that these birds travel is 122.22 miles per day to the south.
Explanation:
Speed is the physical quantity that expresses the variation in position of an object and as a function of time. In other words, speed is a physical quantity that expresses the relationship between the space traveled by an object, the time used for it and its direction.
Speed is expressed mathematically as the quotient between distance and time:

where "v" is the speed of the mobile, "d" is the distance traveled by the mobile, and "t" is the time taken by the mobile to carry out the movement.
In this case:
- d= 11,000 miles
- t=3 months= 90 days (
considering that in 1 month there are 30 days)
Replacing:

velocity = 122.22 
<u><em>The average velocity that these birds travel is 122.22 miles per day to the south.</em></u>
Explanation:
The vertical component the velocity of the projectile is 15 m/s x sin 30 = 7.5 m/s.
The body is accelarating downwards at 10 m/s^2.
This means that every second its upward velocity reduces by 10 m/s.
So if the body is travelling upwards at 7.5 m/s then how long does it take for the velocity to become 0?
(7.5 m/s) / (10 m/s^2) = 0.75 s
