Explicație pas cu pas:
2/3 + 1/8 = 16/24 + 3/24 = 19/24
1 - 19/24 = 24/24 - 19/24 = 5/24
5/24....................50 km
1/24....................50 : 5 = 10 km
24/24 = 24*10 = 240 km are traseul
x= distanta totala
⁸⁾2x/3+³⁾x/8+²⁴⁾50=²⁴⁾x
16x+3x+1.200=24x
24x-16x-3x=1200
24x-19x= 1200
5x= 1200
x= 1200:5
x= 240 km ( distanta totala )
