How many square meters are in each wall? ** Each wall is 2*3=<<2*3=6>>6 square meters
How many minutes does each wall take? ** So each wall takes 6*10=<<6*10=60>>60 minutes to paint
How many hours does each wall take? ** So it takes 60/60=<<60/60=1>>1 hour to paint each wall
How many hours does it take to paint the room? ** That means in total it takes 5*1=<<5*1=5>>5 hours to paint
How many hours does John have left? ** So he has 10-5=<<10-5=5>>5 hour left after finishing painting
