|______|__|__|__|__|__|__|__|__|__| = total = 180 km

|_____|                                                    = prima zi

              |__|__|                                         = a doua zi

                         |_|_|                               = a treia zi

                                   |_|_|_|_|            = a patra zi

                                                      |__|   = a cincea zi

A = ¼*180 km=45 km

Au ramas 180-45=135 km

B=135*2/9=30 km

Au ramas 135-30=105 km

C=105*2/5=42 km

Au ramas 105-42=63 km

D=63*4/7=36 km

Au ramas 63-36=27 km

E=27 km

45+30+42+36+27=180
