What two base quantities are used to measure speed

The base quantities that are used to measure speed are distance and time.

Explanation

In quantitative calculation, speed of an object can be measured by knowing the distance traveled in a given time.

S= D/T

The distance is the actual stretch covered by the object.

The SI unit of distance meters (m).

Time is the actual time taken to cover the distance.

The SI unit of time is seconds (s).

So speed is a derived quantity stating the rate at which change in distance can be observed.

The unit of speed is m/s.

The base quantities used to measure speed are distance and  time.

Explanation:

Speed is defined as the rate of change of distance with time. It is given by the  equation        

SI unit of speed is  

Speed is a scalar quantity that has only magnitude and no direction. The vector equivalent of speed is velocity which is defined as the rate of change of displacement with time.

Since speed is scalar it can only have positive values. But velocity can have negative and positive values.
