James does chores around the class.  There are 3 bedrooms, 1 living room, and 2 bathrooms to clean.  The bedrooms each take 20 minutes to clean.  The living room takes as long as the 3 bedrooms combined.  The bathroom takes twice as long as the living room.  He also cleans the outside which takes twice as long as cleaning the house.  He splits the chores with his 2 siblings who are just as fast as him.  How long, in hours, does he work?
How long does it take to clean the living room? ** It takes 3*20=<<3*20=60>>60 minutes to clean the living room
How long does it take to clean the living room? ** So it is 60/60=<<60/60=1>>1 hour
How long does it take to clean the bathroom? ** The bathroom takes 1*2=<<1*2=2>>2 hours
How long does it take to clean the inside? ** So all together the inside takes 1+1+2=<<1+1+2=4>>4 hours
How long does it take to clean the outside? ** The outside takes 4*2=<<4*2=8>>8 hours
How long does it take to do the chores? ** So the chores take 4+8=<<4+8=12>>12 hours
How many ways does he split the chores? ** He splits it 1+2=<<1+2=3>>3 ways
How long does he work? ** So he works 12/3=<<12/3=4>>4 hours
