Answer 1

Answer:

Mars is about 224.4 million kilometers from the Sun.

Explanation:

This statement is incorrect. The correct one is presented below:

Mars is 1.5 AU from the Sun. About how many kilometers is Mars from the Sun?

The Astronomical Unit (AU) is a length unit used in Astronomy to measure distances between planets of the Solar System and from the Sun whose units equals to $1.496\times 10^{8}\,km$. Since Mars is 1.5 AU from the Sun, we converting this value into kilometers by means of the following simple rule of three:

$x = 1.5\,AU\times \frac{1.496\times 10^{8}\,km}{1\,AU}$

$x = 2.244\times 10^{8}\,km$

Mars is about 224.4 million kilometers from the Sun.
