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.
