Question

Calculate the distance to the ocean floor if sound traveling at 1500 meters per second makes the round trip to the bottom and back in 10 seconds.

7500 meters
150,000 meters
15 meters
150 meters

Answer 1

7500

Step-by-step explanation:

Answer 2

7500 m

Step-by-step explanation:

The speed is the same both directions, so the sound takes 5 seconds to reach the bottom and 5 seconds to return to the surface.

Distance = speed × time

d = (1500 m/s) (5 s)

d = 7500 m
