Essay

Makena and Renee work for a home cleaning company and they form a team. In each room, there are two broad cleaning areas: floor and windows. Makena can do a floor in 40 minutes and windows in 25 minutes. Renee does floors in 30 minutes and windows in 30 minutes.
a. How long does it take to clean an apartment with 4 rooms if Makena takes 2 rooms and Renee takes 2 rooms, assuming that if one finishes earlier she takes a break waiting for the other?
b. Later on, they decide that if one finishes earlier she would help the other to finish so that they can move on to another client. How long does it take now to finish?
c. After a while, they realize that it is better if one does the floors in all rooms and the other does the windows. How long does it take now?
