Question

Venus' orbital speed is approximately 210 kilometers in 6 seconds. Earth's orbital speed is approximately 270 kilometers in 9 seconds. Which planet travels at a faster speed per second?

Answer 1

We know that

• Venus' orbital speed is 210 kilometers in 6 seconds.

,

• Earth's orbital speed is 270 kilometers in 9 seconds.

First, we have to divide the numbers to find the ratio

$\begin{gathered} \frac{210}{6}=35 \\ \frac{270}{9}=30 \end{gathered}$

As you can observe, Venus has greater speed because it's 35 kilometers per second.

Hence, the answer is Venus.
