It will take 0.556 seconds for an echo to reach one's ears
<h3>Calculating the time to hear an echo</h3>
From the question, we are to determine how long it would take an echo to reach one's ears
From the formula,
NOTE: To hear an echo, the sound will travel to and fro, hence, it will cover twice the distance
From the given information,
Distance = 92.0 m
NOTE: Speed of sound in air at 0 °C ≅ 331 m/s
Putting the parameters into the formula, we get
Time = 0.556 secs
Hence, it will take 0.556 seconds for an echo to reach one's ears.
