Question

i need help

Answer 1

1 average person = 3 hours of painting a sized room

 

Since you have 5 times as much paint, you have the following:

5 x 3 = 15 hours

 

Since you have 4 people to help paint, you divide the work among them to get the answer: 15/4 = 3 3/4 hours.  If you want it in hours and minutes, then the answer would be the following:

3 3/4 hours = 3 45/60 hours = 3 hours 45 minutes.

Answer 2

Average person would take 3 man-hours to paint one room.

Five times the area would require 15 man-hours of work.

If 4 average persons did the job it would take 15/4 = 3 3/4 hours to finish the job.
