Question

I really need help with this, I would be happy if someone could help me.

You fly round-trip from Los Angeles to New York. The flight takes 6 hours each way and covers a distance of 4800 km. What were your average speed and average velocity on this round-trip flight?

Answer 1

Average speed = 800 km/h and average velocity = 0

Step-by-step 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,

`v=(9600\ km)/(12\ h)\\\\v=800\ km/h`

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.
