Răspuns :
a) Daca Marcel va merge pana la scoala 185 m atunci Radu va face pana la scoala 185 + 75 = 260 m .Acum daca fac drumul si inapoi atunci:
Radu : 260 x 2 =560 m dus-intors
Marcel: 185 x 2 =370m dus-intors
b)Daca Radu face pana la scoala 185 m atunci Marcel va face pana la scoala 185 - 75 = 110 m .Acum daca fac drumul si inapoi:
Radu: 185 m x 2 = 370 m dus-intors
Marcel: 110 m x 2 = 220 m dus-intors
Radu : 260 x 2 =560 m dus-intors
Marcel: 185 x 2 =370m dus-intors

A) dus-intors: 185*2=370 m (Marcel)
185+75=260*2=520 m (Radu)
B) dus-intors: 185*2=370 m (Radu)
185-75= 110 *2= 220 m (Marcel)
185+75=260*2=520 m (Radu)
B) dus-intors: 185*2=370 m (Radu)
185-75= 110 *2= 220 m (Marcel)
