Answer: 7 people need 16 minutes to paint 4 walls.
Step-by-step explanation:

So, we will apply "time and work formula" i.e.
where,
H denotes number of hours or minutes,
D denotes number of days
M denotes number of men
W denotes work done them,
So, we need to calculate number of minutes for 7 people to paint 4 walls,
So, 7 people need 16 minutes to paint 4 walls.
The picture shows how this would look as a triangle.
In this case, we would use tan. x is the opposite side, and 80 is adjacent.
tan(85.7) = x/80
13.299.. = x/80
x = 1,064 feet
