## Multiple Traveler Questions

Summary
The essence of solving complex word problems involving multiple travelers or trips with multiple segments in GRE prep is encapsulated through the application of the D = RT (Distance = Rate x Time) equation.
• Each traveler and each trip segment must be assigned its own D = RT equation to accurately model the problem.
• Solving these problems often requires setting up multiple equations and using algebraic techniques to solve for two unknowns, typically through substitution or elimination methods.
• 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 is crucial for solving problems involving multiple variables and conditions in GRE quantitative sections.
• The process of solving these equations can reveal the distance between two points, the time taken for a journey, or the speed of a traveler.
