Plug the distance into the formula. Using the Standard Speed Equation 1. For general purposes the equation speed distancetime or s dt is usually the easiest way to calculate speed.
An easy way to remember the formulae is to put distance speed and time or the letters D S and T into a triangle.
Assess what information you are given. To find distance speed is beside time so distance is speed multiplied by time. Simply put if you drove 60 kilometres for one hour it would look like this. 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 in kmh the result will be in kilometers.
