It takes 36 minutes for 7 people to paint 4walls. How many minutes does it take 9 people to paint 7 walls?

1 answer:

4 0

The concept that can be used in order to determine the answer to this item is that of equating the man-hours for each walls.

Case 1: (36 minutes)(7people) / 4 walls

Simplifying,
63 people-minutes/wall

Using this calculated value for the next case,

63 people-minutes/wall = (9 people)(x minutes)/7 walls

The value of x from the equation is 49 minutes.

Thus, the answer is 49 minutes.
