Answer 1

Answer:

v = 340 m/s

Explanation:

Given that,

A herdsman yelling out to a fellow herdsman heard his voice reflected by a cliff 4s later.

The cliff is 680 m away

We need to find the velocity of sound in air.

Velocity = distance/time

Distance = 2 × 680 = 1360 m

$v=\dfrac{1360\ m}{4\ s}\\\\=340\ m/s$

So, the velocity of sound in air is 340 m/s.
