In a submarine fitted with a SONAR, the time delay between generation of a signal and reception of its echo after reflection from an enemy ship is observed

to be 73.0 seconds. If the speed of sound in water is 1450 m^{s –1} , then calculate the distance of the enemy ship.


We will use the formula 2d=v*t
where v= velocity of SONAR in water
t= time taken.
d=52925m=52.925 km
1 5 1
The distance of enemy ship is 52.925
