1.	A train takes t sec to perform a journey, if travel for t/ n sec with uniform acceleration then for ((n-3)/(n))t sec with uniform speed v and finally it comes to rest with uniform retardation. Then average speed of train
Answer» `(3n - 2) (V)/(2N)` `(2n - 3)(v)/(2n)` `(3n - 2) (v)/(3n)` `(2n-3) (v)/(3n)` ANSWER :B
