Question

Find the average speed from t = 0 - 12 seconds.0.917 m/s1.25 m/s1.33 m/s0.583 m/s

Answer 1

Given data:

* The initial value of the time is 0 s.

* The final value of the time is 12 s.

Solution:

The average speed from the graph is,

`s=\frac{\text{Total distance}}{\text{ Total time taken}}`

Substituting the known values,

`\begin{gathered} s=(7)/(12) \\ s=0.583\text{ m/s} \end{gathered}`

Thus, the average speed from 0 to 12 seconds is 0.583 m/s.

Hence, fourth option is the correct answer.
