Problem Solving - Paper Run Math Puzzle
Emily has started a new job delivering newspapers in her local area. She has decided she will use her skateboard to travel between houses. She takes the time to plan the most effective and efficient paper run route. Emily needs to deliver to every house on the map and ride over every street line at least once, with as little total travel as possible. She can start and end at any house on the map. However, some street lines will need to be travelled more than once. This is the difficulty. Can you help Emily find the shortest route for her paper run?
