Question 830638: jake can wallpaper a room in 5 hours and maura can do it in 6 hours. What part of the job can they do working together for 1.5 hours Found 2 solutions by JulietG, richwmiller:Answer by JulietG(1812) (Show Source):
You can put this solution on YOUR website! From the problem, we're told that Jake wallpapers 1/5 room per hour, and that Maura wallpapers 1/6 of a room per hour.
.
Together, they wallpaper 1/5 + 1/6 per hour.
Let's give them a common denominator by making it 30ths (6*5)
Jack wallpapers 6/30 in one hour; Maura wallpapers 5/30 in one hour. Together they can wallpaper 11/30 in one hour.
But we're looking for 1.5 hours. Simply multiply the numerator (top number) by 1.5.
In 1.5 hours, they can wallpaper 16.5/30 of a room, or .55
