Answer:
27 minutes to complete the painting of 4 walls
Step-by-step explanation:
since 16m with 9p --> 8 walls
x minutes with 4p --> 6 walls?
let x= minutes
6 walls painted=(8/144 walls painted per minute)x
simplify
x= 6 divided by (8/144)
x=108 minutes (to complete 6 walls)
108/4=
27 minutes to complete the painting of 4 walls
