How to solve proportional relationships word problems?

Solving problems involving proportional relationships, especially with speed, usually requires understanding the relationship between distance, speed, and time. Here’s a step-by-step guide to solve such problems:

Understand the Relationship The basic formula connecting distance (d), speed (s), and time (t) is:
Speed = Distance/Time
or
𝑠 = 𝑑/𝑡
If you know any two of the three quantities, you can solve for the third.
Identify What You’re Given
Determine which of the three variables (distance, speed, time) are provided in the problem.
If the problem involves proportionality, recognize that if one variable changes, the other variables will change in a specific way, maintaining the relationship.
Set Up the Proportion
If the problem states that two scenarios are proportional (e.g., the speed is constant), you can set up a proportion: Distance₁/Time₁ = Distance₂/Time₂
This can also be rearranged to solve for any missing variable.
Solve the Proportion
Cross-multiply and solve the equation for the unknown variable.
Check and Interpret the Solution
Verify that the solution makes sense in the context of the problem.
Interpret the result, ensuring it answers the question asked.

Tips:
Constant Speed: If the speed remains constant, the relationship between distance and time is directly proportional.
Units: Always ensure the units are consistent (e.g., miles per hour, kilometers per hour).
