Using proportions, it is found that the blue team paints faster.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
For this problem, to find which team paints faster, we have to find the team that has the highest proportion of square meters painted per hour, dividing these amounts as given in the problem. Hence the proportions are found as follows:
- Blue team: 15/6 = 2.5 square meters per hour.
- Red team: 8/4 = 2 square meters per hour.
2.5 > 2, hence, due to the higher value of the proportion, the blue team paints faster.
