It describes how quickly or slowly an object moves from one place to another. The standard (SI) unit of speed is meters per second (m/s), but it can also be expressed in other units, such as kilometers per hour (km/h), miles per hour (mph), or feet per second (ft/s), depending on the context or the country's measurement system.

In order to use the above speed, distance & time calculator, or do such math on your own, you will need to know two out of three metrics: speed, distance, time. You will need to convert the metrics to the same time and distance units, e.g. miles, kilometers, meters, yards, feet, and hours, minutes or seconds. For example, if you have speed in mph (...
The formula for average speed, also called average velocity in physics and engineering, is: v = d / t where v is the velocity, d is the distance, and t is the time, so you can read it as Speed = Distance / Time. As noted above, make sure you convert the units appropriately first, or use our speed calculator which does that automatically. The result...
The formula for distance, if you know time (duration) and the average speed, is: d = v x t where v is the velocity (average speed), t is the time and d is distance, so you can read it as Distance = Speed x Time. The result will depend on the unit of the speed metric, for example if speed is given in mph, the result will be in miles, if it is given ...
The time, or more precisely, the duration of the trip, can be calculated knowing the distance and the average speed using the formula: t = d / v where d is the distance travelled, v is the speed (velocity) and t is the time, so you can read it as Time = Distance / Speed. Make sure you convert the units so both their distance and time components mat...
Say you travelled a certain distance with a car or another vehicle and you want to calculate what its average speed was. The easiest way to do that would be by using the calculator above, but if you prefer, you can also do the math yourself. Either way, you need to know the distance to a satisfactory approximation, for which you can use a map (e.g....
Jul 29, 2024 · Sound moves through the air at a speed of around 343 meters per second, which is 1234.8 km/h or 767 mph (at 20 °C / 68 °F). It means that a sound wave in air needs about 2.9 seconds to travel one kilometer, or 4.7 seconds to travel a mile — this data might be useful for storm-hunters to determine the lighting distance. In 2012, Austrian ...
Problemas de movimiento rectilíneo uniforme (MRU) En esta página vamos a resolver 15 problemas de movimiento rectilíneo uniforme (MRU), es decir, problemas de móviles que se mueven en línea recta y a velocidad constante. La fórmula del MRU es. siendo. d d la distancia recorrida, v v la velocidad del móvil y. t t el tiempo que dura el ...
If the distance was 200 kilometers and it took 4 hours to cover it, the speed was 200 / 4 = 50 km/h (kilometers per hour). As you can see, to work out your speed in km/h or mph just apply the speed formula with the relevant units for distance and time. This is how to calculate average speed of a car, bike, boat, or any other vehicle or object.
