Lesson Summary:

In this lesson on work problems, the concept of work is introduced through an example of painting a house. The relationship between rate, time, and work is explained using rate*time=work or job done. The lesson then moves on to a work problem involving two people, Tom and Don, who work at different rates to paint a house. The transcript walks through how to find the time it takes for them to complete the job working together.

Lesson Description:

How long does it take for two people to do the same job together?

    This video is a great starting place for learning about how work problems are set up and solved. You will be introduced to the idea of rate of working and work done in a time frame. This then leads into finding how long it would take two people to complete the same job together, a very common and often difficult problem in Algebra.
