Answer:

i. Average velocity = 11.11 m/s

ii. Displacement of the bus is 20000 m due east.

Step-by-step explanation:

The displacement of an object is the distance covered towards a definite direction, while the velocity of an object is the rate of its displacement in a given time.

average velocity = [tex]\frac{displacement}{time taken}[/tex]

But,

20 km = 20 000 m

30 minutes = 30 x 60

                   = 1800 s

So that,

average velocity  = [tex]\frac{20000}{1800}[/tex]

                             = 11.1111

average velocity = 11.1 m/s

The displacement of the bus is 20 km due east.
