Jawaban:

Diketahui:

Kedalaman laut (h) = 2.250 meter

Cepat rambat bunyi () di air laut (v) = 1.400 meter/sekon

Waktu yang dibutuhkan untuk bunyi pantul kembali (t) = 4 sekon

Untuk menghitung waktu yang diperlukancontinued:

Solution:

We can start by using the formula:

distance = rate x time

First, let's find the total distance traveled by the sound:

total distance = distance down + distance up

total distance = 2h = 2 x 2,250 meters = 4,500 meters

Next, let's find the time it took for the sound to travel the total distance. We can rearrange the formula to solve for time:

time = distance / rate

time = 4,500 meters / (1,400 meters/sec x 2)

time = 1.61 seconds

However, this is only the time it took for the sound to travel one way (down to the ocean floor). To find the total time it took for the sound to travel down and back up to the ship, we need to double the time:

total time = 2 x 1.61 seconds

total time = 3.22 seconds

Therefore, the time it took for the sound to travel from the source on the ocean floor to the ship and back is approximately 3.22 seconds.
