well 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. . .

im assuming the question is saying that you hear your echo 2 times

You need the time between the 2 sounds

yey!!! 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. . .

why we multiplied it by 4 @theyatin @amistre64 @henpen

the 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

imagine you and a friend throwing a ball back and forth; how far does the ball travel relative to your positions if you catch it 2 times and throw it 2 times?

im thinking that it pertains to the rebound that you hear. and not really referencing words perse

if you stand in an echoy place and give a brisk woot!! you can hear how many times it echos back at you

one of them old dead scientist guys used a long hallway that he knew the length of in order to estimate the speed of sound that way
