To calculate the average velocity of the vehicle during interval CD, I would need the specific values of the velocity at the beginning and end of that interval from the graph.
However, since I cannot see the graph, here is a general approach you can follow:
- Identify the velocities at the beginning and end of interval CD.
- Use the formula for average velocity, which is:
\[ \text{Average Velocity} = \frac{\text{Final Velocity} - \text{Initial Velocity}}{\text{Time Interval}} \]
If you provide the velocities at the two time points of interval CD, I can help you calculate the average velocity.
