Answer 1

a /******/------/------/-------/
b           /****/------/------/
c                  /*****/--50--/
50*2=100
100:2=50
50*3=150
150:3=50
50*4=200

Answer 2

x-lungimea drumului

x/4 in prima zi
x-x/4=(4x-x)/4=3x/4 restul
3x/4/3=3x/4×1/3=x/4 in a doua zi
3x/4-x/4=2x/4 noul rest
2x/4/2=2x/4×1/2=x/2×1/2=x/4 in a treia zi
2x/4-x/4=x/4 noul nou rest
x/4=50
x=4×50=200 km
