Final answer:
Using the given speed of sound in seawater of 1450 m/s, it will take approximately 5.17 seconds for sound to travel 7500 meters in water at 25°C.
Step-by-step explanation:
To determine the time it would take for sound to travel through 7500 meters of water at 25°C, we need to know the speed of sound at that temperature. However, the student's question relates to examples where the speed of sound in seawater is given as 1450 m/s. Using this speed, we can calculate the time it takes for sound to travel a certain distance using the formula: time = distance / speed. For 7500 meters, the calculation would be:
time = 7500 m / 1450 m/s = 5.1724 seconds.
So, it would take approximately 5.17 seconds for sound to travel 7500 meters in water, assuming the speed of sound in water at 25°C is similar to the given value of 1450 m/s.
