The length of a planet's orbit around a
star is approximately 24,130,000 km.
It takes the planet about 1440 Earth
days to complete a full orbit.
What is the planet's average speed in
kmh ¹ to 3sf?

Respuesta :

Speed is the ratio of distance and time. The planet's average speed is 698.206 kmph.

What is speed?

The speed is the distance covered by an object at a particular time. Therefore, it is the ratio of distance and time.

[tex]\rm{Speed = \dfrac{Distance}{Time}[/tex]

The length of a planet's orbit around a star is approximately 24,130,000 km. Also, the time it takes for the planet to revolve is 1440 days, where each day has 24 hours. Therefore, the speed of the planet in km per hour is,

Speed = (24,130,000)/(1440 × 24 hours) = 698.206 kmph

Hence, the planet's average speed is 698.206 kmph.
