Question

It takes 54 minutes for 4 people to paint 6 walls. How many minutes does it take 6 people to paint 7 walls?​

Answer 1

94,5 minutos

Explanation:

54/4=13,5

13,5/6=2,25 pessoa por parede

2,25*6*7=94,5

Answer 2

Answer: 81minutes

Explanation:

Let the missing value be x

54 minutes = 4 people

X = 6 people

Cross multiply

4x = 324

Divide both sides by 4

x = 324/4

x = 81

It will take 81minutes for 6 people to paint 7 walls.

I hope this helps.
