Answer:

[tex]\boxed{\text{0.76m/s}}[/tex]

Explanation:

[tex]\text{Average speed} = \dfrac{\text{total distance}}{\text{total time}}[/tex]

Total distance = 2 m + 30 m = 32 m

      Total time = 2 s  + 40 s   = 42 s

[tex]\text{Average speed} = \dfrac{\text{32 m}}{\text{42 s}} = \textbf{0.76 m/s}\\\text{The average speed of the object is $\boxed{\textbf{0.76m/s}}$}[/tex]
