In physics, speed refers to the magnitude of the velocity of an object.
Speed is the total distance traveled divided by the time it takes to travel it[1].
Note that speed is a scalar, therefore it has no direction or sign.
Like velocity, units for its measurement are meter/second and more commonly in informal circumstances kilometer/hour and mile/hour.
