What does this calculator find?
How long a journey takes, if you know the distance and your speed. The rule is time = distance ÷ speed (t = d/v).
// physics › Speed, Distance & Time
Time (from Speed & Distance)
Find the time taken from distance and speed, or solve for distance or speed, using t = d / v.
t = d / v
Frequently asked questions
Can you show an example?
You need to cover 100 metres at 20 metres per second. Time = 100 ÷ 20 = 5 seconds. So it takes 5 seconds.
How do I find distance or speed instead?
Rearrange the same formula: distance = speed × time, and speed = distance ÷ time. Pick what you want in the 'Solve for' box.
Why is it called 'time-kinematic'?
Just to tell it apart from the clock-and-calendar time tools. This one is about motion — finding travel time from speed and distance.
What units should I use?
Distance in metres and speed in metres per second give time in seconds. Kilometres with km/h give hours. Keep both inputs in matching units.
Where do I see this in real life?
Estimating how long a drive or a walk will take: take the distance, divide by your usual speed, and you have the time.
