To calculate the distance to the ocean floor, we can use the speed of sound in water and the total time for the round trip.

  1. Speed of sound in water: 1500 meters per second.
  2. Total time for round trip: 10 seconds.

First, we need to find out how long it takes for the sound to reach the ocean floor (one way). Since the time given is for the round trip, we can divide this by 2:

\[ \text{Time to bottom} = \frac{10 \text{ seconds}}{2} = 5 \text{ seconds} \]

Next, we can calculate the distance to the ocean floor using the formula:

\[ \text{Distance} = \text{Speed} \times \text{Time} \]

Substituting the values:

\[ \text{Distance} = 1500 \text{ m/s} \times 5 \text{ seconds} = 7500 \text{ meters} \]

Thus, the distance to the ocean floor is 7500 meters.
