In this lesson, the focus is on work problems and specifically on using equations to find out how long a job will take. The problem presented is that it takes Jim six days to frame a house, but only four days if he works with his son, and the question is how long would it take his son working alone to frame the house? The lesson proceeds to explain how to write and solve equations to figure out the answer, and ultimately arrives at the answer that it would take his son 12 hours to frame the house alone.
