The distance of the cliff from where you are is determined as 3,430 m.
<h3>Distance of the cliff</h3>
Apply the formula for echo.
v = 2d/t
where;
- v is speed of sound at 20 ⁰C = 343 m/s
- d is distance = ?
- t is time = 20 s
2d = vt
d = vt/2
d = (343 x 20)/2
d = 3430 m
Thus, the distance of the cliff from where you are is determined as 3,430 m.
