3Question 3.
What does time mean speed measure?
- Instantaneous speed of vehicles
- Average speed over time
- Speed on a specific road segment

4Question 4.
True or False: Time mean speed is always equal to space mean speed.
- True
- False
Show hintHide hint
Reflect on the definitions of both measurements.
Question 5.
In a speed study, speeds of a sample of vehicles were collected, with values of 60, 65, 70, 75, and 80 mph. Calculate the time mean speed and discuss how it might differ from a space mean speed in this scenario.
