Two speakers are placed 500 meters away from each other. A person stands right in the middle of the two speakers. One of the speakers sends a sound wave traveling at 343m/s towards the person standing in the middle and the other speaker sends a sound wave traveling at 342m/s. How long after the person in the middle hears the first sound wave will he hear the second wave ( ) (please answer the question with unit of seconds)

the second wave will be heard at after the first sound wave.

Explanation:

Given that:

two speakers are placed 500 meters away from each other and a person is standing in the middle;

that implies that the distance of the speed of the wave travelling  is divided into two equal which is 250 m

Now; from the first speaker, time to reach sound wave is;

Also from the second speaker; time to reach sound wave is;

Thus, the second wave will be heard at after the first sound wave.

the answer is a 3.8cm
