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.
- The process often involves setting up multiple equations and solving them using techniques for two equations with two unknowns, such as substitution and elimination.
- Practical examples illustrate how to apply these strategies to calculate distances and times, demonstrating the method's effectiveness in solving varied motion problems.
- Key insights include the importance of breaking down problems into manageable parts and the utility of algebraic methods in finding solutions.
- The content underscores the necessity of understanding and applying algebraic techniques, such as substitution and elimination, to efficiently solve GMAT word problems.
