Question

use the data to answer the question below.
is the following statement about our solar system true or false? mercury orbits the sun at more than four times the speed of saturn.
true
false
planet average distance from the sun (km) average orbital speed (km/s)
mercury 5.79 x 10^7 47
venus 1.08 x 10^8 35
earth 1.50 x 10^8 30
mars 2.28 x 10^8 24
jupiter 7.79 x 10^8 13
saturn 1.43 x 10^9 10
uranus 2.87 x 10^9 7
neptune 4.50 x 10^9 5

Explanation:

Step1: Find Mercury's orbital speed

Mercury's speed is 47 km/s.

Step2: Find Saturn's orbital speed

Saturn's speed is 10 km/s.

Step3: Calculate four - times Saturn's speed

$4\times10 = 40$ km/s.

Step4: Compare

Since $47>40$, Mercury's orbital speed is more than four - times Saturn's speed.

Answer:

true
