Answer 2

Fie x lungimea drumului

x/4 -> a parcurs in prima zi

x-x/4=3x/4 -> a ramas de parcurs dupa prima zi

3x*2/4*3=6x/12=x/2 -> a parcurs in a doua zi

3x/4-x/2=x/4-> a ramas de parcurs dupa a doua zi

x/4*2=x/8 -> a parcurs in a treia zi

x=x/8+x/2+x/4+60

x=60+(x+4x+2x)/8

x=60+7x/8

7x/8-x=-60

(7x-8x)/8=-60

-x/8=-60

x=8*60

x=480 km ->lungimea totala a drumului

x/4=480/4=120 km ->a parcurs in prima zi

x/2=480/2=240 km ->a parcurs in a doua zi

x/8=480/8=60 km_ a parcurs in a treia zi

60 km-> in a patra zi
