16 traffic cones are placed in a straight line at a distance of 10 meters from one another. We want to paint a continuous line on the road going from the first to the last cone. Knowing that to paint 100 meters of continuous line 6 liters of paint are needed, how many liters of paint are needed to complete this job?
Pick one
Solution
The answer is (B). 16 traffic cones determine 15 segments 10 meters long, for a total of 150 meters of line, and to paint it one and a half times the paint is needed compared to the 6 liters for 100 meters, that is 9 liters.
