A sonar device uses sound to measure distance under water. The speed of sound in water is about 1,400 m/s. If a ship sends a signal it reflects back off of an object such as another submarine or a whale and takes 3 seconds to return, how far away is the object?
if the three seconds is time going down, and time coming up, then
distance=1/2 (3)(1400) m

To calculate the distance, we can use the formula:
Distance = Speed × Time
In this case, the speed of sound in water is given as 1,400 m/s, and the time it takes for the signal to return is 3 seconds.
Plugging in these values into the formula, the calculation would be:
Distance = 1,400 m/s × 3 s
The product of 1,400 m/s and 3 s is 4,200 meters.
Therefore, the object is approximately 4,200 meters away from the ship.
