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.
