Question
The arc lengths of a directed graph of a project are as shown in the figure. The shortest path length from node 1 to node 6 is _______.

Correct answer
7 to 7
Solution
To find the shortest path from node 1 to node 6, we evaluate all possible directed paths:
1.Path 1-2-4-6:
2.Path 1-2-5-6:
3.Path 1-2-5-4-6:
4.Path 1-3-5-6:
5.Path 1-3-5-4-6:
6.Path 1-2-3-5-6:
7.Path 1-2-3-5-4-6:
The shortest path is 1-2-5-4-6 with a length of 7.Continue learning with Success Tracker
