  5. The first thing to do is work out the speed of the train: 142 km is 142,000 metres and an hour is 3600 seconds, so the speed of the train is 142,000 m / 3600 s = 39.44 m/s (this can be calculated using the first calculator in this page). The time the train travels is 43 x 60 s = 2580 s.

    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....
