Word Problems
Summary
The essence of solving GRE word problems involving multiple travelers or trips with multiple segments lies in the strategic use of the distance equals rate times time (D=RT) equation for each unique scenario.
- Each traveler and each segment of a trip requires its own D=RT equation.
- Solving complex problems often involves setting up multiple equations and then using techniques for solving systems of equations, such as substitution and elimination.
- 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 effectively can solve problems involving varying speeds, distances, and times for multiple travelers or trip segments.
- The algebra module is recommended for further learning on substitution and elimination techniques.
