To calculate the distance between the boat and the shoal of fish, we can use the equation:
Distance = (Speed of Sound * Time) / 2
where:
- Speed of Sound is the speed at which sound waves travel through water, given as 1600 m/s.
- Time is the time taken for the sound pulse to travel to the fish and back, given as 0.2 seconds.
Let's plug in the values and calculate the distance:
Distance = (1600 m/s * 0.2 s) / 2 Distance = (320 m) / 2 Distance = 160 meters
So, the shoal of fish is approximately 160 meters away from the boat.
