Salvamontistul

Proposed by wmutexOffline
(6 comments)4.505 times displayed

Un salvamontist urca pe o carare, incepand drumul de la poalele muntelui la ora 10 si terminand drumul in varful muntelui la ora 18. A doua zi coboara pe aceeasi carare, plecand din varful muntelui la ora 10 si terminand drumul la poalele muntelui la ora 14.

Aratati ca, daca salvamontistul nu se intoarce din drum, exista un loc pe carare prin care trece in acelasi moment al zilei, la urcare si la coborare.
