Best ResponseYou've already chosen the best response.0well its very tough i see it as if minimum frequency gets us time t=0.05s minimum and as we have 2 syllables 0.05*2=0.1 ( as i have studied in link given by gazi) so the distance must be velocity* time=33meter but to strike wall and come back it becomes 66 as total. . . but here question is asking for the distance of surface so i am not quite sure. . .

Best ResponseYou've already chosen the best response.0yey!!! that justifies my answer 16.5m which when multiplied by 4 gets an answer of 66m again explaining it. . . we can hear minimum 20hz that leads to T=0.05sec and thus the distance leads to velocity * time = 330 * 0.05=16.5 thus when multilied by 4 gets 66m. . .

Best ResponseYou've already chosen the best response.1the distance traveled between the "wall" and the source is quadrupled in order to hear the echo twice, as i pictured it up. assuming that im reading the question correctly to begin with
