  • How do you solve word problems about the amount it time it takes to do a certain amount of work?
  • How do you write an solve an equation about two people doing the same job together?
  • How can you check your solution to a word work problem?
  • If it takes Jim 6 days to frame a house alone, and it takes 4 days if he works with his son, how long would it take his son, working alone, to frame the house?
  • If you know how long it takes someone to do a job alone and how long it takes with another person, how can you figure out how long it takes the other person to do the job?
  • How can you estimate how long it will take to complete a task before solving?
  • How can you solve 2/3 + 4/x = 1?
This video takes the idea of writing and solving equations to figure out how long it takes to do a job, and it spins it a little. This time, you know the time it takes one person and the time it takes together, and you have to figure out how long it would take the other person alone. This could be very confusing, but this video makes it very clear.
