Hi dear 

____________________________________________________________

Suppose that the distance from enemy sub - marine = x 

Then , The Total distance covered by wave  in water = 2x 

We know , Velocity = Distance / Time 

                            

ATQ , 

Velocity of sound wave  × time = total distance covered by sound wave in water 

1450 × 200  = 2x 

x = 1450 × 200 / 2 

  = 1450 × 100 

 

  = 145000 m = 145 km
