Answer:
The answer is simple and this numerical can be solved by using the distance formula .
Explanation:
Use the formula :
Distance/Time = Speed
Substitute the values but remember to take the time as half because if it returns in 3 seconds that means it takes 1.5 secs to reach the surface and remaining 1.5 secs to come back to you .
That is D = 342 * 1.5
D = 513 meters
Hope, this would be helpful to you .
