Question

If you hear your echo 2.00 s after you shout, how far away is the mountain reflecting the sound?

Option a: 343 m
Option b: 686 m
Option c: 171.5 m
Option d: 1372 m

Answer 1

The distance to the mountain reflecting the sound is 686 m.

Step-by-step explanation:

To calculate the distance to the mountain reflecting the sound, we can use the speed of sound and the time it takes for the echo to reach us. Given that the echo is heard after 2.00 s, we can use the formula: distance = speed × time. In this case, the speed of sound is approximately 343 m/s. Plugging in the values, we find that the distance to the mountain is 686 m, which corresponds to option b.
