A particular construction crew places orange barrels on both sides of a road that is under construction such that the centers of adjacent barrels on the same side of the road are 15 feet
apart. If the crew does this for a 1.5 mile stretch of roadway, how many barrels will be placed on
the two sides of the road in total?
First find the number of feet in a mile: 1 mile = 5280 feet
Then multiply that number by the number of miles of road to find the total length of road in feet: 1.5 miles * 5280 feet/mile = 7920 feet
Then divide the total length of road by the distance between barrels to find the number of barrels per side of the road: 7920 feet / 15 feet/barrel = 528 barrels/side
Then double that number to find the total number of barrels, since there are barrels on both sides of the road: 528 barrels/side * 2 sides = <<528*2=1056>>1056 barrels. Answer: \boxed{1056}.
