Answer:

7.69km/hr due east

Explanation:

Given parameters:

Displacement due west  = 3km

Displacement due east = 2km

Time taken  = 8 minutes

Unknown:

Average velocity  = ?

Solution:

Average velocity is the rate of change of displacement with time.

  Velocity  = [tex]\frac{displacement}{time }[/tex]

 Displacement is deals with the start and the end;

  Here, displacement  = 3km - 2km  = 1km due east

Time  = 8min

     60min  = 1hr

       8min = [tex]\frac{8}{60}[/tex]   = 0.13hr

 Average velocity = [tex]\frac{1km}{0.13hr}[/tex]   = 7.69km/hr due east
