To estimate the width of a valley, a climber starts a stopwatch as he shouts. He hears an echo from the opposite side of the valley after 1.0s. The sound travels at 340m/ s. What is the width of the valley?

Respuesta :

[tex]\tt w/d=\dfrac{v.t}{2}[/tex]

w = width/distance

v = velocity

t = time

input the value:

[tex]\tt w=\dfrac{340\times 1}{2}=170~m[/tex]
