Since the total distance for all three of the planets is 196.2 million miles, you would add planet i and planet iii, then subtract that number from 196.2
planet i and planet iii equaled 54.9 million miles, that subtracted from 196.2 equals 141.3
So your answer is 141.3 million miles
I got A it was the same question to. Guess its a different answer for every one
b. Float
Explanation:
A liquid with a specific gravity of less than one with combined with water will definitely float upon it.
Specific gravity is also known as relative density. It is the density of a substance compared to the density of water.
When a substance has higher density than water it will sink in it.
A substance with a density lower than that of water will float and stay on top of it.
