# What Is the Constant Speed Formula?

**The constant speed formula is defined as the ratio of constant distance traveled divided by the amount of time taken to travel the respective distance.** In other words, speed = distance/time.

Constant speed represents how fast something moves. It is commonly calculated by dividing the number of kilometers traveled by the number of hours taken to travel its respective distance. Constant speed assumes that an object travels identical lengths of distance in grouped intervals of time. While constant speed is commonly measured and calculated in units of kilometers per hour, it is also commonly measured in meters per second. Speed is the magnitude of an object's velocity. Velocity measures magnitude and direction, but speed only concerns itself with magnitude.
