Respuesta :
time for job = 3/4 hr/job = 45 minutes to do the whole job.
Answer:
45 minutes
Step-by-step explanation:
1/4 of a hour is 15 mins. Since only 1/3 of the wall is painted, you'll need to multiply the number of mins (15) by 3 and 1/3 by 3. Leaving you with 3/3 of the wall painted in 45 mins. :) i hoped this helped.
