Summary
The content provides a comprehensive guide on solving GMAT word problems involving multiple travelers and trips, emphasizing the strategic use of the Distance = Rate x Time (D=RT) equation.
• Each traveler and trip segment must have its own D=RT equation, facilitating the solution of complex word problems.
• Techniques for solving two equations with two unknowns, such as substitution and elimination, are crucial for finding solutions.
• Three example problems are dissected, demonstrating the application of these strategies to solve for distances and times.
• The importance of breaking down a problem into manageable parts and systematically solving for unknowns is highlighted.
• Advice on solving more complex problems includes paying attention to the details and using algebraic methods to simplify and solve equations.
