Cody can paint a 15 ft. by 18 ft. wall in 50 minutes. He had to paint eight of these walls in his house. If he finished at 7:40 p.m., what time did Cody begin?
The answer is going to be 1:00 because u multiply 50*8=400 minutes 400 Minutes=6 hours and 40 minutes then you subtract 7-6=1 and add the forty minutes Hopes this helps:)
