**The formula for speed is s = d/t, where s equals the speed, d is the distance covered and t is the time it took to cover the distance.** The formula for finding the instantaneous speed at a specific point is found by taking the derivative of the speed equation.

The formula for speed is similar to the formula for velocity, with velocity expressed in vector form. A vector gives the speed and the direction traveled. When considering the speed at a constant acceleration, the formula for speed is the speed when t = 0 plus the product of the acceleration x time, as in the equation v = u + at.
