You don't need to know the acceleration.
For average velocity, just divide the position change vector by the time interval.
Between t= 0 and 2s, the x position increases by 4 m and the y position increases by 4 m.
The average velocity components are
Vx = 2 and Vy = 2.
Do the 5 second case the same way.
