1. [tex] \frac{5}{9} * 36 = 20[/tex], deci mai are de facut 36 - 20 = 16 km.
2. Dupa prima zi, mai are de parcurs [tex]120- (\frac{1}{6} *120)-12=88km[/tex]. A doua zi merge 0,375 * 88km, adica 33km, si inca 7 kilometri, adica 40km in total a doua zi, ramanandu-i doar 88 - 40, adica 48 de km de parcurs in a treia zi.
3. [tex]7,2- \frac{15}{100} * 7,2 = 7,2-1,08=6,12[/tex]lei.
