While You Are Standing In Front Of A Wall You Clap Your Hands And You Can Clearly Hear An Echo From The Wall After 14 Seconds The Speed Of Sound In Air Is 343MS class=

Sagot :

We have the next information

t=1.4 sec

s=speed of the sound 343 m/s

d=?

[tex]d=\frac{s\cdot t}{2}[/tex]

then we substitute the values

[tex]d=\frac{(343)\cdot(1.4)}{2}[/tex][tex]d=\frac{480.2}{2}[/tex][tex]d=240.1m[/tex]

the distance is 240 m
