Question

The orbit of Venus around the sun is treated as a circular path with an average radius of 108.2million km.

The orbital period of Venus is 225 days.
What is the orbital speed of Venus?

Answer 1

Step-by-step explanation:

speed = distance / time

In this case, the distance is the circumference of the circular orbit.

speed = 2πr / t

speed = 2π (108.2×10⁶ km) / (225 days)

speed = 3.02×10⁶ km/day

Or in other units (assuming 1 day = 24 hr):

speed = 1.26×10⁵ km/hr

speed = 35.0 km/s

speed = 35,000 m/s
