To calculate the average speed of the object, we need to find the total distance traveled and the total time taken.

Total distance traveled = 2 m + 80 m = 82 m

Total time taken = 1 s + 40 s = 41 s

Average speed = Total distance traveled / Total time taken

Average speed = 82 m / 41 s

Average speed = 2 m/s

Therefore, the average speed of the object is 2 m/s.
