Answer:

Step-by-step explanation:

Given :

Distance 1 : 50 m east

Distance 2: 25 m west

time : 9 min

formula :

Average speed = total distance / total time

Average velocity = displacement / time

Solution :

Average speed = d/ t

= 50 m + 25 m / 9 min

= 75 m / 9 min ( convert minutes to seconds)

1min = 60 sec

9 × 60 = 540seconds

= 75m /540s

= 0.14m/s

Average velocity = d/ t

= 50 m east + 25 m west / 540 s

= 50m +( -25) m / 540 s

= 25 m east / 540s

= 0.05 m/s east
