Question

Un turist a parcus in prima zi 4/13 din intregul traseu, ceea ce reprezinta 80km.In ziua a doua a parcus de 1 1/3 ori mai mult decit in a treia.Citi kilometri a parcurs turistul in ziua a doua si citi in a treia?

Answer 1

traseul are a km

in prima zi parcurge 4a/13=80, a=80x13/4=260 km are traseul
, iar in prima zi a parcurs 260x4/13=80 km

in a treia zi a parcurs b km, deci in a doua zi a parcurs bx11/3 km
260-80=180 km a parcurs in ziua a doua si a treia
b+c=180 km are de parcurs in ziua a doua si a treia
dar b=11c/3
11c/3+c=180
14c/3=180, c=3x180/14=3x90/7=27/7 km in a treia zi. 180-27/7=1233/7 in a doua zi
