Answer:
Velocity = displacement / time
Distance = 3t^2 +2t +6 to find distance you need to plug in time = 2 sec
Distance = 3(2)^2 +2(2) +6
Distance = 3(4) +4 + 6
Distance = 12 + 4 +6
Distance = 22 meters 
In this problem the displacement is the distance.
so 
Velocity = 22 meters / 2 second 
Velocity = 11 meters/second
