<math>Speed=\frac{d D}{d t}</math>
<math>Speed=\frac{d D}{d t}</math>
Note that speed is a [[scalar]], therefore it has no direction or sign.
Note that speed is a [[scalar]], therefore it has no direction, and because it is a measure of magnitude, it is never negative.
Like velocity, units for its measurement are [[meter]]/[[second]] and more commonly in informal circumstances [[kilometer]]/[[hour]] and [[mile]]/[[hour]].
