Summary
The essence of solving GRE word problems involving multiple travelers or trips with multiple segments lies in the strategic use of the Distance = Rate x Time (D=RT) equation for each unique scenario.
  • Each traveler and each trip segment must have its own D=RT equation, facilitating the breakdown of complex problems into manageable parts.
  • Solving these problems often requires setting up multiple equations and then employing algebraic techniques such as substitution and elimination to find the unknowns.
  • Practical examples illustrate how to apply these strategies to determine distances and times based on given speeds and conditions.
  • Understanding and applying the D=RT equation in varied contexts is crucial for solving GRE word problems effectively.
  • The content underscores the importance of algebraic skills in manipulating equations to derive solutions.
