Review Questions

• Explain how the concept of time intervals is used in solving age problems.
  • In age problems, the concept of time intervals is often used to establish relationships between the ages of individuals at different points in time. For example, if the problem states that a person's age increased by a certain number of years over a specific time period, this information can be used to set up an equation that represents the relationship between the person's initial age, the time interval, and their final age. Understanding how to use time intervals is crucial for translating the given information into an algebraic equation that can be solved to find the unknown ages.
• Describe the role of algebraic equations in solving age problems.
  • Algebraic equations are essential for solving age problems, as they allow you to represent the relationships between the unknown ages and the given information. By setting up an equation with variables representing the unknown ages, you can then solve for the missing values using algebraic techniques, such as isolating the variable or using substitution. The ability to translate the problem statement into a well-constructed algebraic equation is a key step in successfully solving age problems, as it provides a systematic way to find the unknown ages based on the provided information.
• Analyze how the problem-solving strategy of 3.1 can be applied to age problems.
  • The problem-solving strategy outlined in Section 3.1 can be effectively applied to age problems. This strategy involves understanding the problem, devising a plan, carrying out the plan, and reflecting on the solution. For age problems, this would involve carefully reading the problem statement to identify the relevant information, such as the ages of individuals and the time intervals involved. Then, you would need to devise a plan by setting up an appropriate algebraic equation to represent the relationships between the ages. Carrying out the plan would involve solving the equation, and finally, reflecting on the solution to ensure it makes sense within the context of the original problem statement. By following this structured approach, you can systematically tackle age problems and ensure that your solution is accurate and meaningful.
