Speed is the rate of change of position of an object with time.The average speed of an object in an interval of time is the distance travelled by the object divided by the duration of the interval
Speed = (Total distance covered)/ total time taken
Unit of Distance is meter or Kilometer and that of time is second or hour. Common units of speed are therefore metre/second or m/s or Kilometer/Hour or km/h.Units are always written in singular, that is, km/h and not kms/hrs.
