it will take 6 seconds for him to reach a position of 12 m. at velocity of 2m/s
the velocity of the object is calculated by the formula v = d/t where d is distance travelled and t is time taken.
so here by substituting the values we get 2m/s=12m/t= 6sec.
Whenever a body travels the same distance in the same amount of time, this condition of velocity is referred to as uniform velocity. Alternatively, we might say that a body is said to be moving at uniform velocity when its speed and direction do not fluctuate over time.
