Distance

Find distance from speed and time, or solve for speed or time, using d = v t.

d = v t

Frequently asked questions

What does this calculator find?

How far you travel, if you know your speed and how long you travel for. The rule is distance = speed × time (d = v×t).

Can you show an example?

A car drives at 20 metres per second for 5 seconds. Distance = 20 × 5 = 100 metres. Simple as that.

How do I find speed or time instead?

Rearrange the same formula: speed = distance ÷ time, and time = distance ÷ speed. Pick what you want in the 'Solve for' box.

Is this the same as the Speed calculator?

Yes — it is the same speed-distance-time relationship, just set up to find distance first. Use whichever calculator matches what your question asks for.

What units should I use?

Speed in metres per second and time in seconds give distance in metres. Use km/h with hours for kilometres. Keep both inputs in matching units.

Does this work if speed changes?

This assumes a steady speed. If the speed changes, you would use average speed, or the acceleration calculator for steadily changing speed.
