Echo Sounding: Calculating Ocean Depth Based on Sound Travel Time

On Friday, January 25th, we explore an intriguing question regarding the depth of the ocean floor beneath a ship. By analyzing the time it takes for sound waves to make a round trip (14 seconds) and knowing that sound travels at 1,520 m/sec in sea water, we need to calculate how far below the ship the ocean floor is. Given the options of 21,280 m, 10,640 m, 6,080 m, and 9,120 m, let's solve this fascinating problem through mathematical reasoning, enhancing our understanding of underwater acoustics.
