Question 1
â€‹
â€‹
Develop the tree table from the minimum tree for node 1 shown below.

â€‹
â€‹
Question 2
â€‹
Sketch the network described by the accompanying link table.
Find by observation the 'minimum tree' from node 1 and 2, respectively.
Make a Tree Table for the 'minimum tree' for node 1.

Question 3
â€‹
Based on the tree table given, sketch the minimum tree for node 2.

Question 4
â€‹
â€‹
Six vehicles run time trials on a 1 mile track.
â€‹
The speed for the six vehicles are 10, 20, 15, 16, 25 and 22 mph, respectively.
â€‹

Calculate TMS and SMS based on these speeds.

Which is the correct measure of mean speed in this situation? TMS or SMS.
â€‹
Verify that your answer to 2 above is correct by determining the mean speed from first principles. In other words, calculate the mean speed by the total travel distance and travel time for the six vehicles combined.
