Answer:
Explanation:
The Earth travels around the Sun at a speed of about 29.6 kilometers per second.
To find out the speed at which Mars travels around the Sun, we can use the information given: Mars travels around the Sun at 0.81 times Earth's speed.
To calculate Mars' speed, we need to multiply Earth's speed by 0.81:
29.6 km/s * 0.81 = 23.976 km/s
Therefore, Mars travels around the Sun at approximately 23.976 kilometers per second
