Question

The speeds of sound in air and sea - water are given to be 340 m/s
and 1440 m/s respectively A ship sends a strong signal straight
down and detects its echo after 1 5 sec The depth of the sea at
that point is ____________

Mansi Thakur · Accepted Answer

Let depth of sea be d
Distance covered by signal will be 2d
Speed= 1440m/s
Time taken= 1 5s
Speed= Distance/Time
Distance= Speed x Time = 1440 x 1 5 = 2160 m
2d = 2160
d = 2160/2 = 1080 m

The speeds of sound in air and sea - water are given to be 340 m/s and 1440 m/s respectively. A ship sends a strong signal straight down and detects its echo after 1.5 sec. The depth of the sea at that point is ____________.
