Speed 
This is the rate at which a body covers a distance.
Speed = distance/ time, 
this is an average speed (v) over the distance (s), v = s/t, the SI unit (Standard International unit) of distance is meter, while for time is second, therefore, for speed is meter per second (ms-1), we could have units in centimeters per second and kilometer per hour.

Uniform Speed 
When a body covers equal distances in equal time intervals, no matter how small the time interval…
