Speed, Distance & Time
From a distance and a time, get your average speed in km/h and your pace in minutes per kilometre — the two ways to describe how fast a trip really was.
Two views of one trip
Enter the distance and the time to get the average speed (km/h) and the pace (min/km) — the same journey seen two ways.
It's an average
The result is the average over the whole trip, not your speed at any single moment — stops and traffic are smoothed into one figure.
What is a speed, distance & time calculator?
Distance and time in, speed and pace out
A speed, distance and time calculator turns two everyday measurements — how far you went and how long it took — into your average speed and your pace. Speed is distance per hour (km/h); pace is its inverse, the minutes each kilometre takes (min/km). It is the tool behind travel ETAs, driving averages, and the splits runners and cyclists train by — anywhere a journey has a known distance and a known duration.
Enter a distance in kilometres and a time in hours to get your average speed and pace instantly.
Speed is distance divided by time, and pace is the same relationship turned upside down.
speed = distance ÷ time pace = time ÷ distance × 60With the distance in kilometres and the time in hours, speed comes out directly in km/h. Pace flips the fraction — time divided by distance — and multiplies by 60 to express it in minutes per kilometre. The two always agree: 50 km/h means each kilometre takes 1.2 minutes, because a faster speed is a smaller pace.
Suppose you drive 100 km and it takes 2 hours.
Speed
100 ÷ 2 = 50 — your average speed is 50 km/h.
Pace
2 ÷ 100 × 60 = 1.2 — each kilometre takes 1.2 minutes.
Check
50 km/h and 1.2 min/km describe the same trip: 60 ÷ 50 = 1.2.
The two outputs answer two different questions about the same journey. The average speed (50 km/h for a 100 km trip in 2 hours) is what you compare against a limit or use to estimate an arrival time — multiply it by the hours remaining to get the distance still to cover. The pace (1.2 min/km) is how runners and cyclists think: it tells you the time cost of each kilometre, so multiplying it by the race distance gives a finish time. Remember this is an average over the whole trip, not your speed at any single instant — a 50 km/h average can hide long stretches at 90 and several stops at zero. The same relationship rearranges to whatever you are missing: distance is speed × time, and time is distance ÷ speed, so the one formula covers all three quantities.
The arithmetic is exact, but a couple of practical points are worth keeping in mind.
Averages and consistent units
This calculator gives an average over the entire trip, not instantaneous speed, so it cannot show how your pace varied along the way. It also expects the distance in kilometres and the time in hours: enter minutes as a fraction of an hour (30 minutes is 0.5) and convert the result with a dedicated unit tool if you need miles per hour or metres per second.
