Cosmin are |---|
Eugen are   |---|---|---|---|
                    ⇒  5 * |---| = 35  ⇔ |---| = 35:5 = 7
⇒   Eugeni are 7*4=28 masinute
   iar Cosmin are 7 masinute !

E |-----|-----|-----|-----|
C |-----|                           } 35.

35 : 5 = 7 masinute ( are Cosmin)
7 x 4 = 28 masinute ( are Eugen)
Verificare : 28 +7 = 35.
