(A) Given: Speed of sound in water $(V)$ = $1530 \, m s^{-1}$.Total time taken for the echo to return $(t)$ = $80 \, s$.Let the distance of the obstacle from the submarine be $d$.The sound travels to the obstacle and back to the submarine,covering a total distance of $2d$.Using the formula: $2d = V 	imes t$.Substituting the values: $2d = 1530 	imes 80$.$2d = 122400 \, m$.Therefore,$d = 122400 / 2 = 61200 \, m$.

In a submarine equipped with sonar,the time between the transmission of ultrasonic signals and the reception of the echo after reflection is found to be $80 \, s$. Find the distance of the obstacle from the submarine,given that the speed of sound in water is $1530 \, m s^{-1}$. (in $, m$)
