if planet one is 29.3 miles farther from the sun than planet two, then planet three is 25.4 miles farther from the sun than planet one. When the total of distances for these three planets from the sun is 192.0 miles, how far away from the sun is planet
two?

For lack of a drawing tool, the planets look like this:

**SUN**<-- D2 -->

**P2**<--29.3 -->

**P1**<-- 25.4 -->

**P3**

where the P's are the planets and the # are the distances between as given.

We need to find D2, distance of P2 from the sun.

The sum of the distances of the planets fro the Sun is information given.

D2 = distance of P2 from Sun

D1 = distance of P1 from Sun = D2 + 29.3

D3 = distance of P3 from the Sun = D2 + 29.3 + 25.4

D1 + D2 + D3 = 'total of distances for these three planets from the sun' = 192.0

D1 + D2 + D3 = (D2 +29.3) +(D2) + (D2 + 29.3 + 25.4) =192.0

**D2 = 36 miles DISTANCE OF PLANET 2 FROM THE SUN.**BruceS
