### Lesson: Work, Rate, and Mixture Problems Recap

#### Introduction

Work, rate, and mixture problems are common in algebra and appear frequently in various real-world situations. These problems often involve finding how long it takes to complete a task, determining speed or rate of work, or mixing substances in certain ratios. In this lesson, we’ll revisit how to solve these types of problems and explore online resources that can provide additional approaches and practice.

#### Objectives

- Refresh the approach to solving work, rate, and mixture problems in algebra.
- Understand the formulas and methods used to solve these problems.
- Utilize online resources for practice and alternative problem-solving approaches.

#### Solving Work, Rate, and Mixture Problems

**Work Problems**:- Focus on the rate of work and the time taken to complete a task.
- Use the formula: Work = Rate × Time.
- Example: If a person can complete a task in 5 hours, how much of the task is completed in 1 hour?

**Rate Problems**:- Often involve calculating speed or efficiency.
- Use the formula: Rate = Distance/Time or Rate = Work/Time.
- Example: If a car travels 300 miles in 5 hours, what is its speed?

**Mixture Problems**:- Involve combining substances in a ratio to achieve a desired mixture.
- Focus on the quantities and concentrations of each component.
- Example: How much of a 10% salt solution must be mixed with 2 liters of a 20% salt solution to make a 15% salt solution?

#### Online Resources for Practice

Several online platforms offer structured approaches and exercises for these problem types:

**Khan Academy**(Khan Academy):- Provides detailed tutorials and practice problems on work, rate, and mixture problems.
- Offers step-by-step explanations and interactive exercises.

**IXL Learning**(IXL Math Practice):- Offers a range of problems specifically focused on work, rate, and mixture.
