Question 18

Alice and Ben are participating in the “Healthy Walk Challenge”, where each participant must walk starting from Sunshine Elementary School to Green Park. When they reach Rest Point 1, Alice asks Ben: “How far have we walked so far?”

Ben replies: “We have walked one-third of the distance from here to Rest Point 2.”

After resting, they continue walking. After walking another 18 kilometers, Alice asks again: “How much farther do we have to walk to reach Green Park? I’m getting tired!”

Ben replies: “Only one-third of the distance from here back to Rest Point 2 remains, and then we will be at Green Park.”

How far apart, in kilometers, are Sunshine Elementary School and Green Park?
