by foot from the coast. On a trek like this, each person can
only carry enough rations for five days and the farthest we
can travel in one day is 30 miles. Also, the city is 120
miles from the starting point.
What I am trying to figure out is the fewest number of
persons, including myself, that I will need in our Group so
that I can reach the city, stay overnight, and then return
to the coast without running out of supplies.
How many persons (including myself) will I need to
accomplish this mission?
