Speed is defined as the change of distance with respect to change in time. If a body moves from one point to other point in a unit time, then speed of the object can be measure by dividing the total distance covered by total time consumed. In mathematics it is calculated by taking the derivative of distance with respect to time. The formula for speed is;

S= x/t   ( s, x and t represents the speed, length or distance and time respectively.)

S= change in length/ change in time

S= dX/dt  ( in derivative form)

Speed is a scalar quantity and its unit is meter per sec. If a direction is associated with speed it is known as velocity.

Speed is measured by taking the distance and dividing it by the amount of time it took. Once you do that you will find your speed in miles per hour or mph.
