26.3 Distance and time related questions in linear equations
Distance-Time Word Problems
Model travel word problems with distance equals rate times time, then solve the resulting linear equation.
What You'll Learn
Distance equals rate times time is the core relationship.
Name the unknown time as t and write each distance as rate times t.
When objects move toward each other, their distances add to the total gap.
Solve the resulting linear equation for t.
The same setup adapts to objects moving apart or one catching up to another.
What You'll Practice
1
Solving plane travel problems with wind speed affecting velocity
2
Setting up two-equation systems from distance and time constraints
3
Using elimination to find wind speed and travel distance
4
Converting word problem information into organized data tables
Why This Matters
Distance-time problems appear everywhere from planning road trips to understanding flight schedules. This skill bridges algebra and physics, preparing you for real-world applications in navigation, logistics, and any field involving motion and timing calculations.
