If a sonar echo takes 2.20 seconds to return from a whale, how faw away is the whale?
2*distance=velocitysound*time
Now the trick it knowing the velocity of sound in seawater. You can look it up, however, it varies with salinity, and temperature.
To find the distance of the whale, we can use the formula:
Distance = Speed * Time
In this case, the speed of sound in water is approximately 1500 meters per second. So, we can substitute the speed and time values into the formula:
Distance = 1500 m/s * 2.20 s
Multiplying these values, we get:
Distance = 3300 meters
Therefore, the whale is approximately 3300 meters away.
