Which of the following statements is correct about the average velocit

1.	Which of the following statements is correct about the average velocity of a particle? (The average stands for average of the quantity over the time interval , t_1 " to "t_2 )
Answer» `vecv_("AVERAGE")=(vecv(t_2)-vecv(t_1))/2` `vecv_("average")=veca_("average")(t_2-t_1)` `vecv_("average") = (vecv(t_2)+vecv(t_1))/2` `vecv_("average") = (VECR(t_2)+vecr(t_1))/(t_2-t-1)` Answer :D
