Therefore, Steve will paint house for 20.6 days.
Step-by-step explanation:
We know that Steve determines that it would take them 9 days to paint the house together (if they were both healthy) and that it would take Janet (when healthy) 16 days to paint the house alone.
We conclude that in 1 day Janet painted 1/16 of the house. In nine days, Janet painted 9/16 of house.
