How many hours did Lilly spend cleaning? ** Lilly cleaned for 8 hours / 4 = <<8/4=2>>2 hours.
How many hours did Fiona spend cleaning? ** This means that Fiona was cleaning for 8 hours total cleaning – 2 hours Lilly’s cleaning = <<8-2=6>>6 hours.
How many minutes did Fiona spend cleaning? ** So in minutes, Fiona was cleaning for 6 hours * 60 minutes in an hour = <<6*60=360>>360 minutes.
