Question 885466
divide 3000 by 75 and you get 40.
i believe you have to add 1 to this to get a total of 41.
for example:
assume the rod is 150 meters.
150 meters divided by 75 = 2
that would be one lamppost at the 75 meter mark and 1 at the 150 meter mark, but you need one at the 0 meter mark as well so you have to add 1 to get 3 lamp posts.
solution appears to be 41.
