My question is: Lilly and Fiona are cleaning a room. Between them, it takes 8 hours to clean the room. A quarter of the time spent cleaning was by Lilly and Fiona was responsible for the rest of the cleaning. How long, in minutes, was Fiona cleaning? Your thoughts:
Lilly cleaned for 8 hours / 4 = 2 hours. This means that Fiona was cleaning for 8 hours total cleaning – 2 hours Lilly’s cleaning = 6 hours. So in minutes, Fiona was cleaning for 6 hours * 60 minutes in an hour = 360 minutes. The final answer: 360.
