For a 200 meter long runway, each runway is 1.2 meters wide. How many meters should the starting point of the outer lane be moved forward?

Let the inner radius of two adjacent runways be x and the outer radius be x + 1.22
1 / 2 × 2 π (R + 1.22) - 1 / 2 × 2 π r the starting point of the outer lane should be 3.8308m in front of the inner lane
