REAL-WORLD MATHEMATICS
How to Calculate Distance Using Speed and Time
Use an interactive distance-time graph to understand speed, distance and time with worked real-world examples.
Why this matters in real life
Distance, speed and time are connected. Understanding the relationship helps estimate a journey and interpret distance-time graphs.
Distance, Speed and Time Calculator
See how travel distance changes with time at a constant speed of 60 kilometers per hour.
Model: Distance = 60t
Model assumptions: Assumes a constant 60 km/h, with no stops, traffic or acceleration.

On a distance-time graph, a constant slope means constant speed. A steeper line means more distance traveled per unit of time.
Why constant-speed assumptions matter
Traffic, stops and acceleration make real journeys different from a constant-speed model.
Practice what you learned
Change the slider, make a prediction before looking at the graph, and explain the answer using units. Then try a different input to check whether your reasoning still holds.
