Question

an express train starts from 1 station.after 40 min it crosses a small station which is at a distance of 30 km find the velocity of train (in m/s )when it crosses the station​

Answer 1

Answer:    distance in metre  =  30× 5/18

                                                  = 8.4 m

          time in sec      =      40×60

                                    =      2400sec

   speed/velocity of train   =    dis/time

                                              =    s/t    =   8.4m/2400sec   =  0.0035m/s
