Answer: The corridor is 82.825 meters long

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
