Detailed Solution

The submarine is located 780.81 m from the cliff.
Given,
Speed of the sound in seawater v=1531 m/s
Distance travelled by sonar pulse =2× depth of the sea
                                                      =2d
d= depth of the sea
We are aware that speed × time = distance.
⇒                                                      2d=Speed of sound ×time ⇒                                                      2d=1531 ×1.02 ⇒                                                      2d=1561.62 m, 
⇒                                                        d=1561.62/2
⇒                                                        d=780.81 m
