Question

a mountaineer shouts her name in the valley. half a second later she hears the echo .how far away is the rock which reflecting her voice?(speed of sound in air = 343 m/s​

Answer 1

Answer:

t = 0.5/2 = 0.75

only one way

S = Distance * time

S = 343 x 0.75

S = 275.25 m

Answer 2

Answer:

1372 m or 1 km 372 m

Explanation:

As the speed of sound in air is 343 m/s we will take 686 m/s because it takes same time to reflect back also.

Speed = Distance/ Time

686 m/s = Distance/ 1/2

686 m/s = Distance × 2/1

686×2/1 = Distance

Distance = 1372 m or 1 km 372 m
