Answer:

Assuming the divers are not moving. The diving partner is at 1600 feet.

Explanation:

The sound wave have to  go to the diving partner and return, so its traveling the double of the total distance.

Been X= distance, V= speed, and t= time

[tex]x=v*t\\[/tex]

[tex]WaveTravelDistance=4000*0.8\\\\Distance to the partner=WaveTravelDistance/2\\\\WaveTravelDistance=3200feet\\\\Distance to the partner=1600feet[/tex]
