The document introduces the distance, speed, time triangle formula. It shows that distance equals speed multiplied by time, speed equals distance divided by time, and time equals distance divided by speed. Examples are provided for using the triangle to calculate distance, speed, and time when given two of the three variables. The triangle provides a visual guide to determine which equation to use for the variable you are trying to calculate.

Speed Time
You might get asked to work out
speed, distance or time from the
two other numbers.
𝐷𝑖𝑠𝑡𝑎𝑛𝑐𝑒 = 𝑆𝑝𝑒𝑒𝑑 𝑥 𝑇𝑖𝑚𝑒
𝑆𝑝𝑒𝑒𝑑 =
𝐷𝑖𝑠𝑡𝑎𝑛𝑐𝑒
𝑇𝑖𝑚𝑒
𝑇𝑖𝑚𝑒 =

The distance, speed, time formula triangle
can help you rearrange the
equations correctly.
Distance is at the top and
speed and time below.

3. THE DISTANCE, SPEED, TIME TRIANGLE
Distance?
Speed Time
CALCULATING DISTANCE
If you are asked to calculate Distance
you can see from the triangle
that the speed and time are next
to each other at the bottom.
You multiply speed and
time to get the
distance.
Question:
If speed is 25km/h and time is
3 hours, what is the distance?
x

4. THE DISTANCE, SPEED, TIME TRIANGLE
Distance
Speed? Time
CALCULATING SPEED
If you are asked to calculate Speed
you can see from the triangle
that distance is over time.
You divide distance by time
to calculate speed.
Question:
If distance is 250km and time is 5
hours, what is the speed?
÷

5. THE DISTANCE, SPEED, TIME TRIANGLE
Distance
Speed Time?
CALCULATING TIME
If you are asked to calculate Time
you can see from the triangle
That distance is over speed.
You divide distance by speed
to calculate time.
Question:
If distance is 100m and time is 10
seconds, what is the speed?
÷

Use the formula triangle to answer these questions:
• A cyclist travels at 15km/h for 75km with no stops.
How long did it take?
• A car travels at 60mph for 3 hours. How far did it go?
• The athlete ran 800m in 200 seconds. How fast did
they run?
