    Design a function to calculate the total walking distance around a pentagon-shaped learning station arrangement, where students move sequentially between five equal-length stations during personalized instruction. Given the fixed distance between consecutive learning stations, determine the complete path length students will travel to visit all stations in their learning sequence.
