Answer:
52 Minutes
Step-by-step explanation:
There is one person for every wall in the first part of the question. 5 people for 5 walls.
Therefore, the ratio of walls to people (walls:people) is 5:5.
5 to 5 is a one to one ratio.
5/5 = 1, which means it takes 1 person 52 minute to paint 1 wall.
Likewise, for the second part of the question, there are 20 people for 20 walls.
This is also a 1 to 1 ratio,
which means that it will also take 1 person 52 minutes to paint 1 wall.
Further Explanation:
People. Walls. Time
5. 5. 52
20. 20. 52
5. 20. 52 × 4 = 208
1. 20. 52 × 20 = 1040
20. 10. 52 / 2 = 26
