Question

The echo of your footsteps returns in 0.50 second. How long is the corridor in which you are walking? (Assume the speed of sound for 0°C.)

Answer 1

Answer: The corridor is 82.825 meters long

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

d = (t×c)/2

Where:

Speed of sound c = 331.3 m/s at 0°C

t = time = 0.5 s.

d = distance

Replacing with the values given:

d = (Δt×c)/2 = 0.5×331.3/2 = 82.825 m

The corridor is 82.825 meters long
