The walls

Proposed by matchlessOffline
(9 comments)4.711 times displayed

Stateam intre 2 ziduri paralele cu fata la una dintre ele.Erau cam 15 grade.Am batut o data din palme cat am putut de tare si mi-am auzit primul ecou venind din fata mea la 0,8 secunde.Al doilea ecou a venit din spate dar nu am putut cronometra si am asteptat al treilea ecou. Al treilea ecou s-a auzit foarte incet si a venit tot din spate la 2,4 secunde.
Ce distanta este intre ziduri?
