Question

A ship emits a sound wave to the bottom of the ocean in water, whose speed is 1150 m/s. It takes 3.25 seconds for the sound to return. Determine how deep the ocean is.

Answer 1

it went twice the depth?

2d=1150*3.25
solve for d.

Answer 2

d=vt
d= (1150 m/s)(3.25 s)
d= 3737 x 2
d= 7474 m
