Speed Calculator
🚗 Motion (kinematics). Use the Speed formula to find speed, distance, time: pick the value you want, type the others, and the answer updates as you go.
Speed5 m/s
Pick the ○ next to the value you want to find, fill in the others, and it solves as you type.
What each letter means
| Quantity | Unit |
|---|---|
| Speed | m/s |
| Distance | m |
| Time | s |
Worked example
Find the speed when Distance = 100 m, Time = 20 s.
Using v = d/t: Speed = 5 m/s.
Frequently asked questions
What is the formula for Speed?
v = d/t.
What do the letters stand for, and what units are used?
Speed in m/s, Distance in m, Time in s.
How do you calculate speed?
Put the values into v = d/t. For example, with Distance = 100 m, Time = 20 s, speed = 5 m/s.
Can I solve for a different value?
Yes. In the calculator above, pick the circle next to any value (speed, distance, time) and fill in the others: it rearranges the formula for you.
