- How do you solve word problems about the amount it time it takes to do a certain amount of work?
- If Tom takes 12 hours to paint a house, what is his rate per hour?
- If Tom takes 12 hours to paint a house, and he only works for 6 hours, how much work will he get done?
- If it takes Mary 2/3 of an hour to clean a room, what is her rate per hour?
- If Tom takes 12 hours to paint a house alone, and Don takes 6 hours to paint the house alone, how long would it take if they work together?
- How do you write an solve an equation about two people doing the same job together?
- How can you solve x/12 + x/6 = 1?
- How can you check your solution to a word work problem?
- How can you estimate how long it will take to complete a task before solving?
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.
