31.1. Overview

Try these first

1. 1.

   What is time mean speed?

   Hint

   Think about speed over time.

2. 2.

   Give an example of when space mean speed is used.

   Hint

   Remember it considers distance.

3. 3.

   What is the formula for time mean speed?

   • v = Σv_i / n
   • v = n / Σv_i
   • v = Σt_i / n

   Hint

   Remember it summarizes speeds.

4. 4.

   True or False: Space mean speed is always greater than time mean speed.

   • True
   • False

   Hint

   Think about the implications of averages.

5. 5.

   Given the following traffic data: 4 vehicles traveled at speeds of 30, 40, 50, and 60 km/h. Calculate both time mean speed and space mean speed. Discuss the implications of these speeds in a traffic system.

   Hint

   Consider averages when dealing with diverse speeds.

6. 6.

   A city road shows annual traffic reports suggesting varied speeds due to congestion. Using this data, illustrate how understanding space mean speeds compares with time mean speeds can lead to improved traffic management recommendations.

   Hint

   Focus on comparing different speeds for better insights.
