Writing and solving an equation to find out how long it takes to complete a job.

  • 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 Barry can mow the lawn in 55 minutes, and if his son helps him, it gets done in 30 minutes, how long would it take his son to mow the lawn if he worked alone?
  • How can you estimate how long it will take to complete a task before solving?
  • How can you set up a proportion to solve a word work problem?
  • How do you solve 30/x = 5/11?
  • How do you solve 6/11 + 30/x = 1?
  • How do you solve an equation when x is in the denominator?
This problem is another spin on the traditional work problem. This time, you know how long it takes one person alone and two people together to complete a job, and you have to find how long it would take the other person alone. Again, everything is explained and written out very clearly.

I like it a lot it made it clear, right now I stink at math, but after this website and the people who do the videos I will be the smartest man at math ever alive.
