Question

If planet i is 30.3 million miles farther from the sun than planet​ ii, then planet iii is 24.6 million miles farther from the sun than planet i. when the total of the distances for these three planets from the sun is 196.2 million​ miles, how far away from the sun is planet​ ii?

Answer 1

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
