Answer:
Your average velocity is zero km/h ⇒ answer A
Step-by-step explanation:
Displacement is the change in position of an object
It is measuring from the starting position to the final position of
the object
If the starting and ending position are the same, then displacement of
the object is zero
Velocity of is displacement divided by time
You travel in a circle, whose circumference is 8 kilometers, at an average
speed of 8 kilometers/hour
That means your speed of traveling is 8 km/h
We need to find your average velocity If you stop at the same point
you started
→ Velocity = displacement ÷ time
You end your trip at the same point you started from
That means your displacement is zero
→ Displacement = 0
→ Velocity = 0 ÷ time
Your average velocity is zero km/h
