What is the best strategy for solving multi-part journeys involving different speeds?

1. Distance-Time-Speed table

2. Speed and Time chart

3. Combined speed calculation

4. Distance analysis method

The correct answer is: Distance-Time-Speed table

Using a Distance-Time-Speed table is particularly effective when solving multi-part journeys involving different speeds because it clearly organizes all relevant information. In scenarios with various speeds, the relationship between distance, speed, and time is crucial. The table format allows you to input distances for each segment of the journey, the corresponding speeds, and then calculate the time taken for each part. By structuring the data this way, you can efficiently visualize how each journey segment contributes to the overall travel time and distance. This method also aids in breaking down complex problems into manageable parts, making it easier to understand the impact of varying speeds on the total travel dynamic. Additionally, it simplifies the process of determining travel times if any element changes, as you can quickly adjust one variable and see the result on the overall journey. While other options might provide a different angle for analysis, they don’t offer the comprehensive clarity and straightforward calculations that a Distance-Time-Speed table provides in multi-part journey problems.
