It takes 22 minutes for 10 people to paint 10 walls. How many minutes does it take 14 people to paint 14 walls?

22 minutes

Step-by-step explanation:

The number of minutes and number of people are inversely proportional but the number of people, minutes painted and walls painted are directly proportional. Therefore, it takes 10 people 22 / 10 = 2.2 minutes to paint 1 wall and 2.2 * 14 = 30.8 minutes to paint 14 walls. To find the time it takes 14 people to paint 14 walls, we can set up the following equation:

14 * x = 30.8 * 10 (where x is our answer)

x = 30.8 * 10 / 14 = 22 minutes

Additionally, an easier way to do this is to recognize that 1 person paints 1 wall when 10 people paint 10 walls in 22 minutes so as long as the number of people and walls are the same, it will always take 22 minutes.

so what is the question
