Question

physics experts plz answr this

Answer 1

hey there
average velocity = total displacement / total time taken
500 + 400 +200 / 120 = 9.16 m per second
^_^

Answer 2

15.
speed =(total distance/total time aken)
          = (500+400+200)/(2x60)
          = 9.16 m/s

velocity = (total displacement/total time taken)
             = 500/(2x60)
             =4.16 m/s
