Question

You really have a thing for screaming outside. So on a day where the speed of sound is 343 m/s you go outside and scream at a wall. It takes 0.5 s for you to hear your echo. How far away is the wall that you screamed at?

Answer 1

Speed = Distance/Time
Distance = Speed x Time
343 x 0.5 = 1/2 of 343
343 x 0.5 = 171.5
