Answer:
Average speed = 800 km/h and average velocity = 0
Explanation:
You fly round-trip from Los Angeles to New York.
Distance covered, d = 4800 km in 6 hours
We need to find the average speed and average velocity on this round-trip flight. Round trip means to come back at the initial point.
Total distance = 4800 km + 4800 km = 9600 km
Time, t = 6 h + 6 h = 12 h
Average speed,
[tex]v=\dfrac{9600\ km}{12\ h}\\\\v=800\ km/h[/tex]
So, the average speed is 800 km/h
When it comes back to the initial point. Its displacement is equal to 0. It means its average velocity will be equal to 0.
