The Snowplow Problem
Author: COMAP
Background:
The solid lines of the map represent paved two-lane county roads in a snow-removal district in Wicomico County, Maryland. The bro- ken lines are state highways. After a snowfall, two plow-trucks are dis- patched from a garage that is about 4 miles west of each of the two points (*) marked on the map. Find an efficient way to use two trucks to sweep snow from the county roads. The trucks may use the state highways to access the county roads.
