Question 666084: Math word probelm:
Andy can paint a room in 4 hours, Betty in 6 hours and Chuck in 8 hours. If Betty and Chuck work together for 1 hour and then Andy joins them and they all work together until the room is finished, how long did Andy work? Answer by ewatrrr(24785) (Show Source):
Hi,
Re TY. Thank You for calling attention to the typo.
Andy can paint a room in 4 hours, Betty in 6 hours and Chuck in 8 hours.
Betty and Chuck work together for 1 hour 0r did = 7/24 of the room
17/24 left: together do 13/24 of room per hour = 1.3 hours Andy worked (rounded to the nearest tenth)
