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?

$\tt w/d=(v.t)/(2)$

w = width/distance

v = velocity

t = time

input the value:

$\tt w=(340* 1)/(2)=170~m$
