Answer:
C. Distance and Time
Explanation:
Speed is defined as the distance covered per unit of time. It is a scalar quantity and as such expressed in scalar terms. When we talk about speed, the direction of motion does not matter. We only try to find the rate at which a body moves with time.
It is expressed as:
Speed = [tex]\frac{Distance covered}{Time taken}[/tex]
The SI unit of speed is m/s or ms⁻¹
