Dear student,

Distance travelled from t=0s to t=2s is 20m
Then particle stops for some time and later returns to the starting point
Distance travelled from t=2s to t=10s is 20m
Finally particle moves 10m in negative direction, stops for some time and returns back to origin.
Distance travelled from t=10s to t=12s is 10+10m=20m
Hence total distance travelled=60m.

Hence average speed=\dfrac{60m}{12s}=5m/s

Regards.
