Answer:
v=926.33 km/h
Step-by-step explanation:
We have,
The length of a planet's orbit around a star is approximately 12,450,000 km. It takes the planet about 560 Earth days to complete a full orbit.
It means d = 12,450,000 km
Time, t = 560 Earth days
1 day = 24 hours
560 days = 13440 hours
Planet's average speed can be calculated as :
[tex]v=\dfrac{d}{t}\\\\v=\dfrac{12450000\ km}{13440\ h}\\\\v=926.33\ km/h[/tex]
So, the planet's average speed is 926.33 km/h.
