[(2A)] The given table below (in the first photo) shows the 5 different places that you would like to visit on a particular day. The table below shows the estimated distance (in kilometers per hour) it takes you to travel from one place to another. If you will visit each of these places exactly once, determine the shortest time possible it would take you to do using the Greedy AlgorithmExample (second photo) already provided in the photos below..

Required answer:
Applying the Greedy Algorithm, we find the following Hamiltonian circuit with the
minimum weight (in minutes): HG – GP – PV – VB – BH, or HGPVBH
The obtained minimum time is: 12 + 8 + 12 + 18 + 23 = 73 minutes.
