B4ms
C2ms
D 10 ms

Answer 1

Answer:

$\boxed{\text{0.76m/s}}$

Explanation:

$\text{Average speed} = \dfrac{\text{total distance}}{\text{total time}}$

Total distance = 2 m + 30 m = 32 m

      Total time = 2 s  + 40 s   = 42 s

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