Question

20. An explosion occurs at the upper surface of an ocean. The sound returns to the original site of the explosion 4 seconds later, after having been reflected from the ocean bottom. If the speed of sound in ocean water is 4,800 feet per second, how deep is the water? A. \( 4,800 \mathrm{ft} \). B. \( 9,600 \mathrm{ft} \). C. \( 14,400 \mathrm{ft} \). D. \( 96,000 \mathrm{ft} \).
