30.3.2. Running speed

Try these first

1. 1.

   Define running speed.

   Hint

   Think about how speed is calculated.

2. 2.

   What is the formula for calculating running speed?

   Hint

   Recall the relationship between distance, speed, and time.

3. 3.

   What does running speed refer to?

   • Average speed while in motion
   • Maximum speed reached
   • Speed during stops

   Hint

   Think about how speed is maintained over distance.

4. 4.

   True or False: Spot speed is the average speed of a vehicle over a distance.

   • True
   • False

   Hint

   Consider when speed is measured instantaneously versus over time.

5. 5.

   A vehicle travels 120 km in 1.5 hours. What is the running speed? How would a decrease in running speed affect traffic flow?

   Hint

   Use the formula v = d/t for speed.

6. 6.

   Design a simple traffic plan for an urban area considering optimal running speeds and expected traffic patterns. Explain your rationale.

   Hint

   Think about how speeds can vary at different times of day.
