What two units of measurement are necessary for describing speed?
Speed is calculated by using the formula, speed= distance/time. Let us see which two units of measurement are necessary for describing the speed.
Answer: Meter and second are the two units of measurement that are necessary for describing the speed.
We will see the SI unit of distance and time to answer this question.
The SI unit of distance is the meter and the SI unit of time is second.
So, the SI unit of speed is meter per second.
